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

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

<\/figure>\n
<\/figure>\n

If the cylinder is cut along its height to form a rectangle of dimensions 80 cm X 30 cm, the line joining one vertex to the midpoint of the opposite side is along which the ant has traveled.<\/p>\n

<\/figure>\n

Path travelled by the ant is the dotted line AE.<\/p>\n

Length = $\\sqrt{40^2+30^2}=50$ cm<\/p>\n

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

<\/figure>\n

Imagine the cylinder to be cut across AD in such a way that it forms a rectangle with sides 2*(22\/7)*14 = 88 cm and 66 cm. The required path is the diagonal of the rectangle = 110 cm.<\/p>\n

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

The ratio of base areas is 16:9. So, ratio of the prices is 3\/4*9\/16 = 27\/64<\/p>\n

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

3.14 * 12 * 12 * h = 4\/3 * 3.14 * 3 * 3 * 3
\nSo, h = 0.25 cm<\/p>\n

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

Since the cubes are painted after the 10x11x12 cuboid is cut, all the unit cubes will have their all faces covered with paint.<\/p>\n

So, there will be no cube that will have none of its faces covered by paint.<\/p>\n

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

The number of unit cubes that have no face painted = number of unit cubes that are hidden = (5-2)*(6-2)*(7-2) = 3*4*5 = 60<\/p>\n

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

<\/figure>\n

TSA before the force was applied = 2(3*4 +\u00a04*1+3*1) = 38 sq m<\/p>\n

After the force is applied, the cuboid becomes a parallelopiped with a slant height of 2m and angle of slant surface is 30\u00ba.<\/p>\n

Thus, the height h = 2 sin 30 = 1m<\/p>\n

So the surfaces will be 2 parallelograms with bases 4m and height 1m, 2 rectangles with sides 3m and 2m and 2 rectangles with sides 3m and 4m.<\/p>\n

TSA = 2*(4*1)+2*(3*2)+2*(3*4) = 2*22 = 44 sq m<\/p>\n

% Change in area = (44-38) \/ 38 = 15.78% increase in area<\/p>\n

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

The unit cubes with paint on exactly 2 faces reside on the edges of the cuboid. The cuboid has 12 edges. There are 4 edges of length 12, 4 edges of length 11 and 4 edges of length 10. On the edge with length 12 unit cubes, the number of cubes which have exactly 2 faces covered by paint = 12-2 = 10. Similarly, on the edge with 11 unit cubes, the number of cubes covered by paint on exactly 2 faces = 11-2 = 9. The number of cubes with exactly 2 faces covered by paint on the 10 unit cube edge is 10-2 = 8. Therefore, the total number of unit cubes which have exactly 2 faces covered by paint = 4*(10+9+8) = 4*27 = 108.<\/p>\n
