Question
Ratio of males to females in village ‘A’ and village
‘B’ is 3:4 and 5:6, respectively and number of females in village ‘B’ is 25% more than that in village ‘A’. Find difference between number of males in villages ‘A’ and number of females in ‘A’ if number of males in village ‘B’ is 700.Solution
Number of females in village ‘B’ = 6/5 × 700 = 840 Number of females in village ‘A’ = 840/1.25 = 672 Number of males in village ‘A’ = 3/4 × 672 = 504 Desired difference = 672 – 504 = 168
