Bryan had a total of 750 persimmons and chikoos. He sold
14 of the chikoos and bought another 30 persimmons. In the end, the number of persimmons he had was
25 the number of chikoos. How many more chikoos than persimmons did he have at first?

Comparing between

2x3 =
6 u |
5x3 =
15 u |

The number of chikoos in the end is repeated. Make the number of chikoos in the end the same. LCM of 3 and 5 is 15.
Total number of persimmons and chikoos at first
= 6 u - 30 + 20 u
= 26 u - 30
26 u - 30 = 750
26 u = 750 + 30
26 u = 780
1 u = 780 ÷ 26 = 30
Number of more chikoos than persimmons at first
= 20 u - (6 u - 30)
= 20 u - 6 u + 30
= 14 u + 30
= 14 x 30 + 30
= 420 + 30
= 450
Answer(s): 450
