View Video Solution<\/a><\/p>\n

Solution:<\/b><\/p>\n

$\\left(x^2-5x+7\\right)^{x+1}=1$<\/p>\n

There can be a solution when\u00a0$\\left(x^2-5x+7\\right)=1$ or $x^2-5x\\ +6=0$<\/p>\n

or x=3 and x=2<\/p>\n

There can also be a solution when x+1 = 0 or x=-1<\/p>\n

Hence three possible solutions exist.<\/p>\n

Question 2:\u00a0<\/b>Suppose hospital A admitted 21 less Covid infected patients than hospital B, and all eventually recovered. The sum of recovery days for patients in hospitals A and B were 200 and 152, respectively. If the average recovery days for patients admitted in hospital A was 3 more than the average in hospital B then the number admitted in hospital A was<\/p>\n

View Video Solution<\/a><\/p>\n

Solution:<\/b><\/p>\n

Let the number of Covid patients in Hospitals A and B be x and x+21 respectively. Then, it has been given that:<\/p>\n

$\\frac{200}{x}-\\frac{152}{x+21}=3$<\/p>\n

$\\frac{\\left(200x+4200-152x\\right)}{x\\left(x+21\\right)}=3$<\/p>\n

$\\frac{\\left(48x+4200\\right)}{x\\left(x+21\\right)}=3$<\/p>\n

$16x+1400=x\\left(x+21\\right)$<\/p>\n

$x^2+5x-1400=0$<\/p>\n

(x+40)(x-35)=0<\/p>\n

Hence, x=35.<\/p>\n

Question 3:\u00a0<\/b>If r is a constant such that $\\mid x^2 – 4x – 13 \\mid = r$ has exactly three distinct real roots, then the value of r is<\/p>\n

View Video Solution<\/a><\/p>\n

Solution:<\/b>
\n<\/p>\n

The quadratic equation of the form\u00a0$\\mid x^2 – 4x – 13 \\mid = r$ has its minimum value at x = -b\/2a, and hence does not vary irrespective of the value of x.<\/p>\n

Hence at x = 2 the quadratic equation has its minimum.<\/p>\n

Considering the quadratic part :\u00a0$\\left|x^2-4\\cdot x-13\\right|$. as per the given condition, this must-have 3 real roots.<\/p>\n

The curve ABCDE represents the function\u00a0$\\left|x^2-4\\cdot x-13\\right|$. Because of the modulus function, the representation of the quadratic equation becomes :<\/p>\n

ABC’DE.<\/p>\n

There must exist a value, r such that there must exactly be 3 roots for the function. If r = 0 there will only be 2 roots, similarly for other values there will either be 2 or 4 roots unless at the point C’.<\/p>\n

The point C’ is a reflection of C about the x-axis. r is the y coordinate of the point C’ :<\/p>\n

The point C which is the value of the function at x = 2, =\u00a0$2^2-8-13$<\/p>\n

= -17, the reflection about the x-axis is 17.<\/p>\n

Alternatively,<\/p>\n

$\\mid x^2 – 4x – 13 \\mid = r$ .<\/p>\n

This can represented in two parts :<\/p>\n

$x^2-4x-13\\ =\\ r\\ if\\ r\\ is\\ positive.$<\/p>\n

$x^2-4x-13\\ =\\ -r\\ if\\ r\\ is\\ negative.$<\/p>\n

Considering the first case :\u00a0$x^2-4x-13\\ =r$<\/p>\n

The quadraticequation becomes :\u00a0$x^2-4x-13-r\\ =\\ 0$<\/p>\n

The discriminant for this function is :\u00a0$b^2-4ac\\ =\\ 16-\\ \\left(4\\cdot\\left(-13-r\\right)\\right)=68+4r$<\/p>\n

SInce r is positive the discriminant is always greater than 0 this must have two distinct roots.<\/p>\n

For the second case :<\/p>\n

$x^2-4x-13+r\\ =\\ 0$ the function inside the modulus is negaitve<\/p>\n

The discriminant is\u00a0$16\\ -\\ \\left(4\\cdot\\left(r-13\\right)\\right)\\ =\\ 68-4r$<\/p>\n

In order to have a total of 3 roots, the discriminant must be equal to zero for this quadratic equation to have a total of 3 roots.<\/p>\n

Hence\u00a0$\\ 68-4r\\ =\\ 0$<\/p>\n

r = 17, for r = 17 we can have exactly 3 roots.<\/p>\n

Question 4:\u00a0<\/b>Suppose one of the roots of the equation $ax^{2}-bx+c=0$ is $2+\\sqrt{3}$, Where a,b and c are rational numbers and $a\\neq0$. If $b=c^{3}$ then $\\mid a\\mid$ equals.<\/p>\n

View Video Solution<\/a><\/p>\n

Solution:<\/b><\/p>\n

Given a, b, c are rational numbers.<\/p>\n

Hence a, b, c are three numbers that can be written in the form of p\/q.<\/p>\n

Hence if one both the root is 2+$\\sqrt{\\ 3}$ and considering the other root to be x.<\/p>\n

The sum of the roots and the product of the two roots must be rational numbers.<\/p>\n

For this to happen the other root must be the conjugate of\u00a0$2+\\sqrt{\\ 3}$ so the product and the sum of the roots are rational numbers which are represented by:\u00a0$\\frac{b}{a},\\ \\frac{c}{a}$<\/p>\n

Hence the sum of the roots is 2+$\\sqrt{\\ 3}+2-\\sqrt{\\ 3}$ = 4.<\/p>\n

The product of the roots is\u00a0$\\left(2+\\sqrt{\\ 3}\\right)\\cdot\\left(2-\\sqrt{\\ 3}\\right)\\ =\\ 1$<\/p>\n

b\/a = 4, c\/a = 1.<\/p>\n

b = 4*a, c= a.<\/p>\n

Since b =\u00a0$c^3$<\/p>\n

4*a =\u00a0$a^3$<\/p>\n

$a^2=\\ 4.$<\/p>\n

a = 2 or -2.<\/p>\n

|a| = 2<\/p>\n

Question 5:\u00a0<\/b>For all real values of x, the range of the function $f(x)=\\frac{x^{2}+2x+4}{2x^{2}+4x+9}$ is:<\/p>\n

a)\u00a0$[\\frac{4}{9},\\frac{8}{9}]$<\/p>\n

b)\u00a0$[\\frac{3}{7},\\frac{8}{9})$<\/p>\n

c)\u00a0$(\\frac{3}{7},\\frac{1}{2})$<\/p>\n

d)\u00a0$[\\frac{3}{7},\\frac{1}{2})$<\/p>\n

5)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

View Video Solution<\/a><\/p>\n

Solution:<\/b><\/p>\n

$f(x)=\\frac{x^{2}+2x+4}{2x^{2}+4x+9}$<\/p>\n

If we closely observe the coefficients of the terms in the numerator and denominator, we see that the coefficients of the $x^2$ and x in the numerators are in ratios 1:2. This gives us a hint that we might need to adjust the numerator to decrease the number of variables.<\/p>\n

$f(x)=\\frac{x^2+2x+4}{2x^2+4x+9}=\\frac{x^2+2x+4.5-0.5}{2x^2+4x+9}$<\/p>\n

=\u00a0$\\frac{x^2+2x+4.5}{2x^2+4x+9}-\\frac{0.5}{2x^2+4x+9}$<\/p>\n

=\u00a0$\\frac{1}{2}-\\frac{0.5}{2x^2+4x+9}$<\/p>\n

Now, we only have terms of x in the denominator.<\/p>\n

The maximum value of the expression is achieved when the quadratic expression $2x^2+4x+9$ achieves its highest value, that is infinity.<\/p>\n

In that case, the second term becomes zero and the expression becomes 1\/2. However, at infinity, there is always an open bracket ‘)’.<\/p>\n

To obtain the minimum value, we need to find the minimum possible value of the quadratic expression.<\/p>\n

The minimum value is obtained when 4x + 4 = 0 [d\/dx = 0]<\/p>\n

x=-1.<\/p>\n

The expression comes as 7.<\/p>\n

The entire expression becomes 3\/7.<\/p>\n

Hence,\u00a0$[\\frac{3}{7},\\frac{1}{2})$<\/p>\n

Solution:<\/b><\/p>\n

We have :
\n$x^2-xy-x\\ =22\\ \\ \\ \\ \\ \\ \\left(1\\right)$
\nAnd\u00a0$y^2-xy+y\\ =34\\ \\ \\ \\ \\ \\ \\left(1\\right)$ \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 (2)

\nwe get $\\left(x-y\\right)^2-\\ \\left(x-y\\right)\\ =56$
\nLet (x-y) =t
\nwe get $t^2-t=56$
\n$t^2-t-56=0$
\n(t-8)(t+7) =0

Question 7:\u00a0<\/b>A shop owner bought a total of 64 shirts from a wholesale market that came in two sizes, small and large. The price of a small shirt was INR 50 less than that of a large shirt. She paid a total of INR 5000 for the large shirts, and a total of INR 1800 for the small shirts. Then, the price of a large shirt and a small shirt together, in INR, is<\/p>\n

a)\u00a0175<\/p>\n

b)\u00a0150<\/p>\n

c)\u00a0200<\/p>\n

d)\u00a0225<\/p>\n

7)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

View Video Solution<\/a><\/p>\n

Solution:<\/b><\/p>\n

Let the number of large shirts be l and the number of small shirts be s.<\/p>\n

Let the price of a small shirt be x and that of a large shirt be x + 50.<\/p>\n

Now, s + l = 64<\/p>\n

l (x+50) = 5000<\/p>\n

sx = 1800<\/p>\n

Adding them, we get,<\/p>\n

lx + sx + 50l = 6800<\/p>\n

64x +50l = 6800<\/p>\n

Substituting l = (6800 – 64x) \/ 50, in the original equation, we get<\/p>\n

$\\frac{\\left(6800-64x\\right)}{50}\\left(x+50\\right)=5000$<\/p>\n

(6800 – 64x)(x +\u00a050) = 250000<\/p>\n

$6800x+340000-64x^2-3200x = 250000$<\/p>\n

$64x^2-3600x-90000=0$<\/p>\n

Solving, we get, x=\u00a0$\\frac{225\\pm\\ 375}{8}=\\frac{600}{8}or-\\frac{150}{8}$<\/p>\n

SO, x = 75<\/p>\n

x +\u00a050 = 125<\/p>\n

Answer = 75 + 125 = 200.<\/p>\n

Alternate approach: By options.<\/strong><\/p>\n

Hint<\/strong>: Each option gives the sum of the costs of one large and one small shirt. We know that large = small + 50<\/p>\n

Hence, small + small + 50 = option.<\/p>\n

SMALL = (Option – 50)\/2<\/strong><\/p>\n

LARGE = Small +\u00a050 = (Option + 50)\/2<\/strong><\/p>\n

Option A and Option D gives us decimal values for SMALL and LARGE, hence we will consider them later.
\n<\/strong><\/p>\n

Lets start with Option B<\/strong>.<\/p>\n

Large = 150 + 50 \/ 2 = 100<\/p>\n

Small = 150 – 50 \/ 2 = 50<\/p>\n

Now, total shirts = 5000\/100 + 1800\/50 = 50 + 36 = 86 (X – This is wrong)<\/strong><\/p>\n

Option C –
\n<\/strong><\/p>\n

Large = 200 + 50 \/ 2 = 125<\/p>\n

Small = 200 – 50 \/ 2 = 75<\/p>\n

Total shirts = 5000\/125 + 1800\/75 = 40 + 24 = 64 ( This is the right answer)
\n<\/strong><\/p>\n

Question 8:\u00a0<\/b>Let m and n be positive integers, If $x^{2}+mx+2n=0$ and $x^{2}+2nx+m=0$ have real\u00a0roots, then the smallest possible value of $m+n$ is<\/p>\n

Solution:<\/b><\/p>\n

To have real roots the discriminant should be greater than or equal to 0.<\/p>\n

So, $m^2-8n\\ge0\\ \\&\\ 4n^2-4m\\ge0$<\/p>\n

=> $m^2\\ge8n\\ \\&\\ n^2\\ge m$<\/p>\n

Since m,n are positive integers the value of m+n will be minimum when m=4 and n=2.<\/p>\n
