Raju ate 38\frac{3}{8}part of a pizza and Adam ate 310\frac{3}{10}part of the remaining pizza. Then Renu ate 47\frac{4}{7}part of the pizza that was left. What fraction of the pizza is still left?

Show answer & explanation

Correct answer: D

Explanation

 The correct answer is option 4 i.e. 316\frac{3}{16}.

Let the quantity of the pizza be x units.

Raju ate 38\frac{3}{8}part of a pizza, which implies that 5/8 part of the pizza is still remaining.

Adam ate 310\frac{3}{10}part of the remaining pizza, which implies that 7/10 part of the pizza is still remaining.

 Renu ate 47\frac{4}{7}part of the pizza, which means 3/7 part of the pizza is still remaining.

Remaining part = x × 5/8 × 7/10 × 3/7 = x × 3/16

Required fraction = (3x/16)/x = 3/16.
