Correct Answer: 98. Let length, breadth, height be 10 unit each. ∴ volume of the cuboid = 1000 cube unit volume of the cuboid After percentage increase length = (10 + 10% of 10) = 11 breadth = (10 + 20% of 10) = 12 height = (10 + 50% of 10) = 15 new volume = 11 x 12 x 15 = 1980 cube unit Increased volume = 1980 – 1000 = 980 % = = 98% % = = (198 – 100)% = 98%

The length, breadth and height of a room in the shape of a cuboid are increased by 10%, 20% and 50% respectively. Find the percentage increase in the volume of the cuboid.
