Question 57
Rita and Meeta both are having lunch boxes of a cuboidal shape. Length and breadth of Rita’s lunch box are 10% more than that of Meeta’s lunch box, but the depth of Rita’s lunch box is 20% less than that of Meeta’s lunch box. The ratio of the capacity of Rita’s lunch box to that of Meeta’s lunch box is
Solution
Let length, breadth and height of Meeta's lunch box be 10 cm each
=> Length and Breadth of Rita's lunch box = 11 cm and height = 8 cm
Volume of a cuboid = $$lbh$$
=> Required ratio = $$\frac{11\times11\times8}{10\times10\times10}$$
= $$121:125$$
=> Ans - (D)
