Answer»

(c) ₹122400

From the question it is given that,

Gayatri’s income ₹ 1,60,000 per year

She pays 15% of this as house rent = 15% of ₹ 1,60,000

= (15/100) × 1,60,000

= ₹ 24000

10% of the remainder on her child’s education = 10% of remaining mount of her income

Remaining mount of her income = ₹ 1,60,000 – ₹ 24000

= ₹ 136000

Total amount of her child’s education = 10% of ₹ 136000

= (10/100) × 136000

= 1360000/100

= ₹ 13600

Then, money left with Gayatri = ₹ 1,60,000 – (₹ 24000 + ₹ 13600)

= ₹ 1, 60, 000 – ₹ 37,600

= ₹ 1,22,400
