An alloy contains copper and tin in the ratio 3 : 2. If 250 gm of copper is added to this alloy then the copper in it becomes double the quantity of tin in it. What is the amount (in gm) of tin in the alloy?
Show answer & explanation
Correct answer: D
Explanation

Ratio of copper and tin in an alloy = 3 : 2
A/Q
3x + 250 = 2 × 2x
250 = x
Amount of tin = 2x = 2 × 250 = 500 gm
