Answers & Solutions:<\/strong><\/span><\/p>\n

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

The value of $\\sqrt{2025}$ = 45
\nThe value of $\\sqrt{1152}$ = 34
\nSo, the value closest to $\\sqrt{2028}$ – $\\sqrt{1152}$ = 11<\/p>\n

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

$15625 = 5*3125 = 25*625 = 25^3 = 5^6$
\nHence, $\\sqrt{15625} = 5^3 = 125$
\nTherefore, $\\sqrt{156.25} = 12.5$<\/p>\n

3)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

Let the value of $\\sqrt{Y} = p$. Note that $p$ is positive.
\nTherefore, $p^2 – p = 30$
\nOr, $p^2 – p – 30 = 0$
\nTherefore, $p^2 – 6p + 5p – 30 = 0$
\nTherfore, $(p-6)(p+5)=0$
\nHence, $p=6$ or $p=-5$
\nBut as $p$ is positive, it implies that $p=6$ and $Y=p^2=36$<\/p>\n

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

We know that $a^3 – b^3 = (a-b) \\times (a^2 + ab + b^2) = (a-b) \\times ((a+b)^2 – ab)$
\nIn this case, $21^3 – 19^3 = (21 – 19) \\times (21^2 + 21 \\times 19 + 19^2)$
\nWhich equals $2 \\times ((21+19)^2 – 21\\times 19)$
\nThis equals $2 \\times (40^2 – 399) = 2 \\times (1600-399) = 2 \\times 1201 = 2402$<\/p>\n

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

$\\sqrt{0.01+\\sqrt{0.0967+0.0258}}$ =\u00a0$\\sqrt{0.01+\\sqrt{0.1225}}$ =\u00a0$\\sqrt{0.01+0.35}$ =\u00a0$\\sqrt{0.36}$ = $0.6$<\/p>\n

So the answer is option A.<\/p>\n

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

$f(x)=x^{4}-3x^{3}+2x +5$<\/p>\n

to find the remainder put x=1 in $f(x)$<\/p>\n

$f(1)$=1-3+2+5=5<\/p>\n

\u22345 is the remainder<\/p>\n

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

$(-216 \\times 1728)^{\\frac{1}{3}}$<\/p>\n

=$(-6^{3} \\times 12^{3})^{\\frac{1}{3}}$<\/p>\n

=-72<\/p>\n

8)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

We see that the numbers are distributed around 50.
\nSo we find the differences around 50
\nEstimated mean= 50
\nSum = +6-5-3+11-1+4+2 =14
\nn=7<\/p>\n

Actual mean = 50 + 14\/7 = 52.<\/p>\n

9)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

As per BODMAS rule, we would add the contents of the brackets first.
\n=> 45\/13 *26 + 5
\n26 = 13 * 2
\n=> 45 * 2 + 5
\n=> 90 + 5
\n=> 95<\/p>\n

10)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

f(x) = $x^3-3x^2+2x-a$. f(2) = 0
\n$2^3-(3*2*2)+(2*2)-a = 0$
\n$8-12+4-a = 0$
\na = 0<\/p>\n

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

Since 2a3 is divisible by 11, therefore (2+3-a) should be divisible by 11.
\n5-a = 0 or divisible by 11
\na = 5.<\/p>\n

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

x = 4.232323….
\n100x = 423.23232323….
\n100x-x = 423.2323…-4.2323… = 419
\nx = 419\/99<\/p>\n

13)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

In this sequence each number is multiplied by a prime number 5*2=10,6*3=18,7*5=35,8*7=56,9*11=99,10*13=130.<\/p>\n

14)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

Expression :\u00a019 + 36 x 12 \u00f7 4 – 26 = 5<\/p>\n

(A) :\u00a0+ and –<\/p>\n

$\\equiv19-36\\times12\\div4+26=5$<\/p>\n

L.H.S. = $19-(36\\times3)+26=19-108+26=-63\\neq$ R.H.S.<\/p>\n

(B) :\u00a0x and \u00f7<\/p>\n

$\\equiv19+36\\div12\\times4-26=5$<\/p>\n

L.H.S. = $19+(3\\times4)-26=19+12-26=5=$ R.H.S.<\/p>\n

=> Ans – (B)<\/p>\n

15)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

Expression\u00a0:\u00a0$15 \\times 12 + 40 \\div 40 – 6 = 21$<\/p>\n

(A) :\u00a0+ and x<\/p>\n

$\\equiv15+ 12 \\times 40 \\div 40 – 6 = 21$<\/p>\n

L.H.S. = $15+(12\\times\\frac{40}{40})-6$<\/p>\n

= $15+12-6=21=$ R.H.S.<\/p>\n

=> Ans – (A)<\/p>\n\n
