उत्तर

Gayatri’s income is ₹ 1,60,000 per year. She pays 15% of this as house rent and 10% of the remainder on her child’s education. The money left with her is ₹ 122400.

Explanation:

Income of Gayatri = ₹ 160000  ......[Given]

Money paid as house rent = 15% of 160000

= `15/100 xx 160000`

= ₹ 24000

Remaining amount = 160000 – 24000

= ₹ 136000

Money spent on child’s education = 10% of 136000

= `10/100 xx 136000`

= ₹ 13600

Money left with her = 136000 – 13600

= ₹ 122400
