Quantitative Aptitiude (CLAT) Ratio, Proportion

60 kg of an alloy X is mixed with 100 kg of an alloy Y. If alloy X has lead and tin in the ratio of 3:2 and alloy Y has tin and copper in the ratio of 1:4, then the amount of tin in the new alloy is

53 kgs.

80 kgs

36 kgs.

44 kgs.

Explanation:

60 kg of alloy A has
lead and tin in the ratio of 3:2 so lead=60*3/5=36 kg
and tin=60*2/5=24kg.
100 kg of alloy B contains tin and copper in the ratio 1:4
so tin=100*1/5=20 kg
and copper=100*4/5=80 kg
so total tin on mixing the two
=24+20 =44 kg
