Bryan and Rael gave away the same number of pens. Bryan gave away
35 of his pens while Rael gave
59 of his pens away. Given that Bryan had 24 pens less than Rael at first, how many pens did Bryan have at first?

Bryan |
Rael |
Before |
5x5 = 25 u |
9x3 = 27 u |
Change |
- 3x5 = - 15 u |
- 5x3 = - 15 u |
After |
2x5 = 10 u |
4x3 = 12 u |
The number of pens that Bryan and Rael gave away is the same. Make the number of pens that Bryan and Rael gave away the same. LCM of 3 and 5 is 15.
Number of pens that Bryan had at first = 25 u
Number of pens that Rael had at first = 27 u
Number of pens that Bryan had less than Rael at first
= 27 u - 25 u
= 2 u
2 u = 24
1 u = 24 ÷ 2 = 12
Number of pens that Bryan had at first
= 25 u
= 25 x 12
= 300
Answer(s): 300
