Assertion (A) : The cost of 16 bulbs is ₹ 144. The number of bulbs than can be bought for ₹ 270 is 30.
Reason (R) : In inverse variation, the ratio of one kind of like terms is equal to the inverse ratio of the second kind of like terms.
Both A and R are correct, and R is the correct explanation for A.

Given,
The cost of 16 bulbs = ₹ 144
The cost of 1 bulb = = ₹ 9
Number of bulbs for ₹ 270 = = 30
So, assertion (A) is true.
In inverse variation,
So, reason (R) is true but, reason (R) does not explains assertion(A).
Hence, option 2 is the correct option.
