If each dimension of a cuboid is increased by 4 times, then the total surface area becomes …………….. times the original area. 

Correct option is (D) 16 Let \(l,b\;and\;h\) are length, breadth and height of the original cuboid. After increasing each dimension of cuboid by 4 times, length of formed cuboid \(=4\,l,\) breadth of formed cuboid = 4b and height of formed...

If 36 men can built a wall in 12 days, then 16 men can built the same wall in …………….. days.

Correct option is (A) 27 Given that 36 men can built a wall in 12 days. \(\therefore\) Total work = 36 \(\times\) 12 Let 16 men can built the wall in x days. \(\therefore\) Total work = 16 \(\times\) x \(\because\) Both work...
