Question
Total population of city P and Q is 2720 and 3300
respectively. If the ratio of number of males to females in city is P and Q is 5:3 and 3:2 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 = 5/8 x 2720 = 1700 & Number of females in city Q = 2/5 x 3300 = 1320 Desired difference = 1700 – 1320 = 380
