PSLE The ratio of the number of jackets to that of blouses in a factory outlet was 11 : 4 in the end. After 52 blouses were sold, the ratio of the number of jackets to that of blouses became 6 : 1. What was the total number of jackets and blouses in the factory outlet in the end?

Jackets |
Blouses |
Total |
Before |
11x6 = 66 u |
4x6 = 24 u |
90 u |
Change |
|
- 52 |
|
After |
6x11 = 66 u |
1x11 = 11 u |
77 u |
The number of jackets remains unchanged. Make the number of jackets the same.
LCM of 6 and 11 is 66.
Number of blouses sold
= 24 u - 11 u
= 13 u
1 u = 52 ÷ 13 = 4
Total number of jackets and blouses in the end
= 66 u + 11 u
= 77 u
= 77 x 4
= 308
Answer(s): 308
