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

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

It is given that the radius of cylinder = 6 cm.\u00a0The rectangular solid with a square base is placed in the cylinder such that each of the corners of the solid is tangent to the cylinder wall.<\/p>\n

Therefore, the diagonal of square base =\u00a0the diameter of circular base<\/p>\n

Hence, a$\\sqrt{2}$ = 2*6 = 12 => a = $6\\sqrt{2}$ cm.<\/p>\n

The volume of water = Volume of the cylinder – Volume of the\u00a0rectangular solid<\/p>\n

$\\Rightarrow$ $\\pi*6^2*24$ – $(6\\sqrt{2})^2*20$<\/p>\n

$\\Rightarrow$ $864*\\pi – 1440$<\/p>\n

$\\Rightarrow$ $288(3\\pi – 5)$<\/p>\n

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

\"8\"<\/figure>\n

The radius of sphere is 8 $cm$. Then applying Pythagoras, the radius of base of cylinder is $\\sqrt{15}$\u00a0\u00a0$cm$<\/p>\n

The height of cylinder is given as 14 $cm$. Volume of cylinder is $\\pi$ $r^{2}$h<\/p>\n

$\\frac{22}{7}$* 15*14 = 660\u00a0$cm^3$<\/p>\n

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

Volume of liquid = Volume of cylinder – Volume of rectangular solid<\/p>\n

<\/figure>\n

 <\/p>\n

Volume of cylinder = $\\pi*r^{2}*h$<\/p>\n

=$\\pi*7^{2}*15$ = $735\\pi$<\/p>\n

Volume of rectangular solid = Area of square base * height<\/p>\n

In square ABCD,\u00a0 AC = $\\sqrt{2}$*AB\u00a0 \u00a0 \u00a0 \u00a0 so AB = $\\frac{14 }{\\sqrt{2}}$ = $7\\sqrt{2}$<\/p>\n

Volume of rectangular solid = Area of square base * height\u00a0 = $(AB)^{2}$*height = $(7\\sqrt{2})^{2}*12$<\/p>\n

=\u00a0 $98*12$ = $1176$<\/p>\n

So Volume of liquid = Volume of cylinder – Volume of rectangular solid<\/p>\n

= $735\\pi$ – $1176$ = $147(5\u03c0-8)$<\/p>\n

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

When the paper is rolled along its length, the circumference of the cylinder formed is equal to the length and the height is equal to the breadth of the rectangle.<\/p>\n

Let ‘r’ be the radius and ‘h’ be the height of the cylinder formed.<\/p>\n

$2\\pi*r = 22$ and h = 10<\/p>\n

Hence, the volume of the cylinder = $\\pi*r^2*h$ = $\\dfrac{22}{7}*(7\/2)^2*10$ = 385 $cm^3$.<\/p>\n

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

i. Volume of the parallelepiped of length 5 cm, breadth 3 cm and height 4 cm = 3*4*5 = 60 cm$^3$
\nii. Volume\u00a0 of\u00a0the\u00a0cube of each side 4 cm = 4^3 = 64\u00a0cm$^3$
\niii.Volume\u00a0 of\u00a0the cylinder of radius 3 cm and length 3 cm = $\\pi*3^2*3$ = 84.82 cm$^3$
\niv. Volume\u00a0\u00a0of\u00a0the\u00a0 sphere of radius 3 cm = $4\/3*\\pi*3^3$ = 113.09\u00a0cm$^3$<\/p>\n

Therefore, we can say that\u00a0volumes of the objects in decreasing order =\u00a0iv,iii,ii,i.<\/p>\n

Hence, option A is the correct answer.<\/p>\n

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

Initially in the 10L solution there is 1.5L sugar and 8.5L water.
\nWe know that:-
\nFinal volume of sugar = Initial volume of sugar*(Volume of solution that is not drawn out\/total volume of solution)$^n$
\ni.e $1 = 1.5*(\\dfrac{10-x}{10})^2$ Where x is the volume of the solution drawn out.
\nThus, $200 = 3*(10^2 – 20x + x^2)$
\nSolving we get x $\\approx 1.873$
\nThe closest value in the option is option D.
\nThus, option D is the correct answer.<\/p>\n

7)\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

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

Let us draw an appropriate diagram. Let us assume that ‘R’ is the radius of the hole.<\/p>\n

<\/figure>\n

$\\dfrac{1}{2}$*(Total volume – Volume of the hole) =\u00a0Volume of the hole<\/p>\n

Volume of the hole = $\\dfrac{1}{3}*\\text{Total volume of the rocket}$<\/p>\n

$\\pi*R^2*(8\/3)x$ =\u00a0$\\dfrac{1}{3}*(\\pi*8^2*5x+\\dfrac{1}{3}*\\pi*8^2*3x)$<\/p>\n

$R^2*(8\/3)$ =\u00a0$\\dfrac{1}{3}*(8^2*5+\\dfrac{1}{3}*8^2*3)$<\/p>\n

$R^2 = 48$<\/p>\n

$R$ =\u00a0$4\\sqrt{3}$ cm. Hence, option A is the correct answer.<\/p>\n

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

Volume of tank = $150 \\times 120 \\times 100 = 18,00,000 cm^3$<\/p>\n

Volume of water in the tank = $12,81,600 cm^3$<\/p>\n

Volume to be filled in the tank = $18,00,000 – 12,81,600 = 5,18,400 cm^3$<\/p>\n

Let the number of bricks to be placed in the tank = $x$<\/p>\n

Volume of $x$ bricks = $x \\times 20 \\times 6 \\times 4 = 480x cm^3$<\/p>\n

Each brick absorbs $(\\frac{1}{10})^{th}$ of its volume in water<\/p>\n

=> $x$ bricks will absorb = $\\frac{480 x}{10} = 48x cm^3$<\/p>\n

$\\therefore$ $5,18,400 + 48x = 480x$<\/p>\n

=> $480x – 48x = 432x = 5,18,400$<\/p>\n

=> $x = \\frac{518400}{432} = 1200$<\/p>\n

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

Volume of Cylinder = $\\pi r^2 h = \\pi \\times 7^2 \\times 10 = 490\\pi$<\/p>\n

Now, The solid metal cylinder is re-cast into two cones in the proportion 3 : 4 i.e. the volumes of cone 1 and cone 2 is<\/p>\n

$210 \\pi$ and $280 \\pi$ respectively.<\/p>\n

So, flat Surface area of cylinder before melting = $2 \\pi r^2 = 2 \\pi \\times 7^2 = 98 \\pi$<\/p>\n

Volume of cone 1 = $\\frac{1}{3} \\pi r_1^2 h = 210 \\pi$<\/p>\n

=> $r_1^2 = \\frac{210 \\times 3}{10} = 63$<\/p>\n

Volume of cone 2 = $\\frac{1}{3} \\pi r_2^2 h = 280 \\pi$<\/p>\n

=> $r_2^2 = \\frac{280 \\times 3}{10} = 84$<\/p>\n

Flat surface area of cones = $\\pi r_1^2 + \\pi r_2^2$<\/p>\n

= $\\pi (63 + 84) = 147 \\pi$<\/p>\n

$\\therefore$ Percentage change in surface area = $\\frac{147 \\pi – 98 \\pi}{98 \\pi} \\times 100$<\/p>\n

= $\\frac{1}{2} \\times 100 = 50 \\%$<\/p>\n
