Question

Suma spends one-third of her pocket money on books, and one-ninth of the same on dolls. If her pocket money was worth ₹270, what is the amount of money left after all the purchases?

• A. ₹20
• B. ₹15
• C. ₹200
• D. ₹ 150

Answer 1

The correct option is D ₹ 150

Worth of Suma's pocket money = ₹ 270
Given that Suma spends one-third of her pocket money on books, and one-ninth of the same on dolls.
$⟹$$\text{Amount spent on books=}\frac{1}{3}\times 270=₹90$, and
$\text{Amount spent on dolls =}\frac{1}{9}\times 270=₹30$
$\text{Thus, the amount left after purchase with Suma}=270-(90+30)=₹150$.
