If x and y are in inverse proportion, then (x + 1) and (y + 1) are also in inverse proportion.
False
If x and y are in inverse proportion, then xy = k(constant) e.g. Let x = 2 and y = 3
∴ xy = 2 × 3 = 6. Now, x + 1 = 2 + 1 = 3 and y + 1 = 3 + 1 = 4
Then, (x + 1) (y + 1) = 3×4 = 12 [not in inverse proportion]
Hence, (x + 1) and (y + 1) cannot be in inverse proportion.
