Question

If the cost of 6 candies is ₹ 36 then, find the cost of 10 candies.

• A. ₹36
• B. ₹40
• C. ₹50
• D. ₹60

Answer 1

The correct option is D ₹60

Let the cost of 10 candies be $x$
As the number of candies increase, the cost increases.
Hence the ratio of the number of candies to cost of candies will be in proportion.
Hence, we have
$6:36::10:x$

$x=\frac{36\times 10}{6}$

$x=60$

Hence the cost of 10 candies is ₹ 60
