(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
