Question
If the ratio of the number of persons who purchased
digital clocks in May and June is 5:3, the average number of persons who purchased analog and digital clocks in June is 525 and then find the number of persons who purchased analog clocks in June?Solution
The number of persons who purchased digital clocks in May = 650 x 2 – 750 = 1300 – 750 = 550 The number of persons who purchased digital clocks in June = 550 x 3/5 = 330 The number of persons who purchased analog and digital clocks in June = 525 x 2 = 1050 The number of persons who purchased analog clocks in June = 1050 – 330 = 720
