Linda had 11 more macarons than Usha at first. After Linda ate 3 macarons, she had thrice as many macarons as Usha in the end. How many macarons did Usha have?
| |
Usha |
Linda |
| Before |
1 u |
1 u + 11 |
| Change |
|
- 3 |
| After |
1 u |
1 u + 8 |
Comparing Usha
and Linda in the end |
1 u |
3 u |
The number of macarons that Usha had remains unchanged.
Number of macarons that Linda had in the end
= 3 x 1 u
= 3 u
3 u = 1 u + 8
3 u - 1 u = 8
2 u = 8
1 u = 8 ÷ 2 = 4
Number of macarons that Usha had
= 1 u
= 4
Answer(s): 4
