The cost of 6 apples is ₹240. What would be the cost of 15 apples?
Answer: A
15 apples cost ₹600.
6 apples cost ₹240, so one apple costs ₹40.
\[ 15\times40=600 \]
₹800, ₹640 and ₹840 would need a price per apple that is not 40.
This is a direct proportion: the cost goes up in the same ratio as the number of apples. The number goes from 6 to 15, a factor of 2.5, and 240 × 2.5 = 600. The same result comes from the unit price.
