Justin and Japheth share a bunch of chikoos in the ratio 7 : 4. If Justin gives Japheth 36 chikoos from his share, they will have the same number of chikoos. How many chikoos does Justin have at first?

- 36 |
+ 36 |
After |
7 u - 36 |
4 u + 36 |
If Justin gives Japheth 36 chikoos from his share, they will have the same number of chikoos.
7 u - 36 = 4 u + 36
7 u - 4 u = 36 + 36
3 u = 72
1 u = 72 ÷ 3 = 24
Number of chikoos that Justin has
= 7 u
= 7 x 24
= 168
Answer(s): 168
