|Sub-Topic||Ratio / Inequality|
In this question, we are given
- The numbers x, y, and k are positive.
- Also, x is less than y.
We need to determine
- The possible range of (x+ k) / (y+ k).
Approach & Working
We know that
- x < y
Or, xk < yk
Or, xk + xy < yk + xy
Or, x (y + k) < y (x + k)
Or, x /y< (x+ k) / (y+ k).
Hence, the correct answer is option B.
