Manish and Jhanavi each receive an equal bonus. Manish has 1/2 fraction of allowance as saving accounts, 1/4 of the fraction he spend at the mall. Jhanavi has 1/3 fraction of allowance as saving accounts, 3/5 of the fraction she spend at the mall. If the allowance of each is Rs. 2520, find the amount left with Manish and Jhanavi?'

Manish has Rs630 while Jhanavi has Rs168.

Step-by-step explanation:

The fraction Manish would have left would be subtracting the fraction on savings as well as that spent on the mall. Which would be;

1 - (1/2 + 1/4) = 1 - 3/4 = 1/4

Meaning Manish had 1/4 of his allowance left on him.

Which means 1/4 * Rs. 2520=Rs630

Similarly for Jhanavi, we have:

The fraction left as

1 - (1/3 + 3/5) = 1 - (14/15) = 1/15

Meaning 1/15 of the allowance got remains which is;

1/15 * Rs. 2520 = Rs. 168
