(a) ₹136000
(b) ₹120000
(c) ₹122400
(d) ₹14000

Solution:

Given, Gayatri’s income is ₹1,60,000 per year.

She pays 15% of this as house rent

10% of the remainder on her child’s education.

We have to find the money left with her.

15% of 160000 = (15/100) × 160000

= 15 × 1600

= 24000

Amount left with Gayatri after paying house rent = 1,60,000 - 24,000

= ₹1,36,000

Now, 10% of 1,36,000 = (10/100) × 136000

= 10 × 1360

= 13600

Amount left with Gayatri = 1,36,000 - 13, 600

= ₹122400

Therefore, the required amount is ₹122400
