Question

Eight oranges can be bought for ₹ 10.24. How many more oranges can be bought for ₹ 19.20?

• A. 300US dollars
• B. 222 US dollars
• C. 180 US dollars
• D. 105 US dollars

Answer 1

The correct option is B

222 US dollars

Let the number of oranges that can be bought for ₹ 19.20 be $y$.
More the amount, we can buy more oranges. Hence this is direct proportion.

$\therefore \frac{10.24}{19.20}=\frac{8}{y}$

$\therefore y=\frac{19.20\times 8}{10.24}$
= 15

Hence, 15 - 8 = 7 more oranges can be bought for ₹ 19.20.
