Sale of items in May = 16% of 7500 = 1200
Sale of items in June = 24% of 7500 = 1800
Sale of items in July = 28% of 7500 = 2100
Sale of items in August = 32% of 7500 = 2400
Sale of balls in May = 60% of 1200 = 720
Sale of balls in June = 55% of 1800 = 990
Sale of balls in July = 75% of 2100 = 1575
Sale of balls in August = 40% of 2400 = 960
Then, sale of bats in May = 1200 - 720 = 480
Sale of bats in June = 1800 - 990 = 810
Sale of bats in July = 2100 - 1575 = 525
Sale of bats in August = 2400 - 960 = 1440
In tabular form:
Month | Sale of items |
Total | Balls | Bats |
May | 1200 | 720 | 480 |
June | 1800 | 990 | 810 |
July | 2100 | 1575 | 525 |
August | 2400 | 960 | 1440 |
Sale of bats in May and June together = 480 + 810 = 1290
And the sale of balls in June and August together = 990 + 960 = 1950
Therefore, ratio = 1290: 1950 = 43: 65
