Ahmad had
58 the number of erasers that Jenson had at first. After Jenson gave Ahmad 44 of his erasers, Ahmad had
34 the number of erasers that Jenson had. How many erasers did Jenson have in the end?

Jenson |
Total |
Before |
5x7 = 35 u |
8x7 = 56 u |
13x7 = 91 u |
Change |
+ 4 u |
- 4 u |
|
After |
3x13 = 39 u |
4x13 = 52 u |
7x13 = 91 u |
The total number of erasers that Ahmad and Jenson had at first and in the end remains unchanged. Make the total number of erasers the same. LCM of 13 and 7 is 91.
Number of erasers that Jenson gave Ahmad
= 39 u - 35 u
= 4 u
4 u = 44
1 u = 44 ÷ 4 = 11
Number of erasers that Jenson had in the end
= 52 u
= 52 x 11
= 572
Answer(s): 572
