Question 30

The incomes of A and B are in the ratio of 3:2 and their expenditures are Rs. 14.000 and Rs. 10,000 respectively. If A saves Rs. 4000. then B's savings will be:

Solution

Let say, income of A and B are 3k and 2k respectively.

A's expenditure 14000 Rs.

So, his savings=(3k-14000) Rs.

So,$$3k-14000=4000.$$

or,$$3k=18000.$$

or,$$k=6000.$$

So,B's income=$$2\times6000=12000.$$

So,B's savings=(12000-10000)=2000 Rs.

B is correct choice.
