Fanny had 19 more tarts than Usha at first. After Fanny ate 3 tarts, she had five times as many tarts as Usha in the end. How many tarts did Usha have?

Usha |
Fanny |
| Before |
1 u |
1 u + 19 |
| Change |
|
- 3 |
| After |
1 u |
1 u + 16 |
Comparing Usha
and Fanny in the end |
1 u |
5 u |
The number of tarts that Usha had remains unchanged.
Number of tarts that Fanny had in the end
= 5 x 1 u
= 5 u
5 u = 1 u + 16
5 u - 1 u = 16
4 u = 16
1 u = 16 ÷ 4 = 4
Number of tarts that Usha had
= 1 u
= 4
Answer(s): 4
