If x percent of a is same as y percent of b, then what percent of a is z percent of b?
General Mental Ability, Quantitative Aptitude and StatisticsPercentages
- Azx/y
- Bxy/z
- Cyz/x
- Dx/(yz)
Explanation
x% of a equals y% of b gives xa/100 = yb/100, so b = xa/y. Then z% of b = (z/100).(xa/y) = zxa/(100y). As a percentage of a this is (zxa/(100y))/a x 100 = zx/y.
