Question
Total population of city P and Q is 3410 and 4620
respectively. If the ratio of number of males to females in city is P and Q is 7:4 and 4:3 respectively, then find the difference between number of males in city P and number of females in city Q.Solution
Number of males in city P = 7/11 x 3410 = 2170 & Number of females in city Q = 3/7 x 4620 = 1980 Desired difference = 2170 – 1980 = 190
