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

Let the side of the smallest square be x.<\/p>\n

According to statement 1,$10x\\geqslant 60$<\/p>\n

$x\\geqslant 6$<\/p>\n

According to statement 2, $7x*6x\\leq 1512$<\/p>\n

$x\\leq 6$<\/p>\n

From both the statements x = 6 and the answer can be determined.<\/p>\n

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

Let the side of the square which is cut be x.<\/p>\n

<\/p>\n

Volume of the cuboid so formed =$(10-2x)^2*x$<\/p>\n

Put x = 1, 2, 3 and so on till 10<\/p>\n

Maximum volume would be at x = 2<\/p>\n

Volume of the cuboid so formed =$(10-2*2)^2*2 = 72$<\/p>\n

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

Diagonal of 8th square will be = 16
\nSide of 8th square = $\\frac{16}{\\sqrt2}$
\nDiagonal of 7th square will be = 14
\nSide of 7th square = $\\frac{14}{\\sqrt2}$<\/p>\n

Difference in areas =\u00a0$(\\frac{16}{\\sqrt2})^2 – (\\frac{14}{\\sqrt2})^2$ = 30
\n4)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

Length of side of $S_{n + 1}$ = Length of diagonal of $S_n$<\/p>\n

=>\u00a0Length of side of $S_{n + 1}$ =\u00a0$\\sqrt{2}$ (Length of side of $S_{n}$)<\/p>\n

=> $\\frac{\\textrm{Length of side of }S_{n + 1}}{\\textrm{Length of side of }S_n} = \\sqrt{2}$<\/p>\n

=> Sides of $S_1 , S_2 , S_3 , S_4,…….., S_n$ form a G.P. with common ratio, $r = \\sqrt{2}$<\/p>\n

It is given that, $S_3 = ar^2 = 4$<\/p>\n

=> $a (\\sqrt{2})^2 = 4$<\/p>\n

=> $a = \\frac{4}{2} = 2$<\/p>\n

$\\therefore$ $n^{th}$ term of G.P. = $a (r^{n – 1})$<\/p>\n

= $2 (\\sqrt{2})^{n – 1}$<\/p>\n

=$2^[{\\frac{n+1}{2}}]$<\/p>\n

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

<\/figure>\n

Area of $S_1 = 8$ sq. units<\/p>\n

=> Side of $S_1 = PS = \\sqrt{8} = 2 \\sqrt{2}$ units<\/p>\n

Similarly, Side of $S_2 = CD = \\sqrt{9} = 3$ units<\/p>\n

=> $a + b = 3$<\/p>\n

In $\\triangle$ PDS<\/p>\n

=> $b^2 + a^2 = 8$<\/p>\n

=> $b^2 + (3 – b)^2 = 8$<\/p>\n

=> $b^2 + 9 + b^2 – 6b = 8$<\/p>\n

=> $2b^2 – 6b + 1 = 0$<\/p>\n

=> $b = \\frac{6 \\pm \\sqrt{36 – 8}}{4} = \\frac{6 \\pm \\sqrt{28}}{4}$<\/p>\n

=> $b = \\frac{3 + \\sqrt{7}}{2}$\u00a0\u00a0\u00a0\u00a0 $(\\because b > a)$<\/p>\n

=> $a = 3 – \\frac{3 + \\sqrt{7}}{2} = \\frac{3 – \\sqrt{7}}{2}$<\/p>\n

$\\therefore \\frac{b}{a} = \\frac{\\frac{3 + \\sqrt{7}}{2}}{\\frac{3 – \\sqrt{7}}{2}}$<\/p>\n

= $\\frac{3 + \\sqrt{7}}{3 – \\sqrt{7}} \\approx 15.9$<\/p>\n

<\/figure>\n

To find : $(BD)^2 + (BE)^2 + (BF)^2 = ?$<\/p>\n

AC = 80 m<\/p>\n

AD = DE = EF = FC = 20<\/p>\n

Let $AB = a$ and $BC = b$<\/p>\n

In $\\triangle$ ABC<\/p>\n

$(a)^2 + (b)^2 = (80)^2$<\/p>\n

Also, $(BE) = 1\/2 (AC) = 40 $<\/p>\n

=> $BE = 40$<\/p>\n

Using Apollonius theorem in $\\triangle$ ABE, as AD = DE<\/p>\n

=> $(AB)^2 + (BE)^2 = 2 [(BD)^2 + (AD)^2]$<\/p>\n

=> $(BD)^2 + 20^2 = \\frac{1}{2} (a^2 + 40^2)$ ——–Eqn(I)<\/p>\n

Similarly, for $\\triangle$ BEC, as EF = FC<\/p>\n

=> $(BE)^2 + (BC)^2 = 2 [(BF)^2 + (FC)^2]$<\/p>\n

=> $(BF)^2 + 20^2 = \\frac{1}{2} (b^2 + 40^2)$ ——–Eqn(II)<\/p>\n

Adding eqns (I) & (II), we get :<\/p>\n

=> $(BD)^2 + (BF)^2 + 20^2 + 20^2$ $= \\frac{1}{2} (a^2 + 40^2 + b^2 + 40^2)$<\/p>\n

=> $(BD)^2 + (BF)^2 + 20^2 + 20^2$ $= \\frac{1}{2} (80^2 + 40^2 + 40^2)$<\/p>\n

=> $(BD)^2 + (BF)^2 = 4800 – 800 = 4000$<\/p>\n

$\\therefore$ $(BD)^2 + (BE)^2 + (BF)^2 = 4000 + 40^2$<\/p>\n

= $4000 + 1600 = 5600$<\/p>\n

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

\"\"
\nAs seen in the fig. we have a right angled triangle with sides \u00a0r ,r-10 , r-20.<\/p>\n

Using pythagoras we have $r^2 = (r-10)^2 + (r-20)^2$.<\/p>\n

Solving the equation,\u00a0we get r = 10 or 50.<\/p>\n

But 10 is not possible , so r = 50.<\/p>\n

Hence radius is 50.<\/p>\n

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

Area of triangle CEF = 1\/2 * length of rectangle\/3 * breadth of rectangle = Area of rectangle\/6
\nSo, required ratio = 1:6<\/p>\n

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

<\/p>\n

Let AB = BE = x<\/p>\n

Area of triangle ABE = $x^2\/2$ = 14; we get x = $\\sqrt{14}$<\/p>\n

So we have side BC = 4*$\\sqrt{14}$<\/p>\n

Now area is AB*BC = 14 *4 = 56 $cm^2$<\/p>\n

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

<\/p>\n

Let the center be O and the point at which the semicircle intersects CD be P.<\/p>\n

Let the radius of the semicircle be R and the circle be r.<\/p>\n

OP = R and OC = R$\\sqrt{2}$<\/p>\n

OC – OT = CC’ – TC’<\/p>\n

$R\\sqrt{2} – R – 2r$ = $r\\sqrt{2} – r$<\/p>\n

=> $R\\sqrt{2} – R$ = $r\\sqrt{2} + r$<\/p>\n

=> r = $\\frac{(\\sqrt{2}-1)R}{\\sqrt{2}+1}$<\/p>\n

=> r = $(\\sqrt{2}-1)^2$R<\/p>\n

Ratio of areas will be $r^2 : \\frac{R^2}{2}$ = $2(\\sqrt{2}-1)^4$ : 1<\/p>\n
