35 as many buttons as Usha. After Cole gave away 89 buttons, he had 95 less buttons than Usha. How many buttons did Usha have?

| Before |
3 u |
5 u |
| Change |
- 89 |
|
| After |
3 u - 89 |
5 u |
Usha had 95 more buttons than Cole in the end. So, if Cole had another 95 buttons, he would have the same number of buttons as Usha.
5 u = 3 u - 89 + 95
5 u - 3 u = 95 - 89
2 u = 6
1 u = 6 ÷ 2 = 3
Number of buttons that Usha had at first
= 5 u
= 5 x 3
= 15
Answer: 15
