Two numbers a and b are inversely proportional to each other. If a increases by 100%, then b decreases by
Explanation:
Given that ‘a’ and ‘b’ are inversely proportional
∴ a ∝ 1/b ⇒ a × b = constant
Hence, if a is doubled (i.e., increased by 100%) b needs to become half.
∴ % change in b = (1/2 - 1) × 100% = 50%.
Hence, option (b).
