Simon had
35 as many buttons as Usha. After Simon bought another 8 buttons, he had 16 less buttons than Usha. How many buttons did Simon have at first?

Simon |
Usha |
Before |
3 u |
5 u |
Change |
+ 8 |
|
After |
3 u + 8 |
5 u |
Usha had 16 more buttons than Simon in the end. So, if Simon had another 16 buttons, he would have the same number of buttons as Usha.
5 u = 3 u + 8 + 16
5 u - 3 u = 8 + 16
2 u = 24
1 u = 24 ÷ 2 = 12
Number of buttons that Simon had at first
= 3 u
= 3 x 12
= 36
Answer: 36
