Four hours ago, a stallholder started his day with some mangoes and chikoos in the ratio of 8 : 7. There were 315 chikoos. Some of the mangoes were bought by Dana. As a result, the number of mangoes became
35 of the chikoos.
- How many mangoes did the stallholder have at first?
- How many chikoos did the stallholder have to sell in order to have an equal number of mangoes and chikoos?

Mangoes |
Chikoos |
Before |
8x5 = 40 u |
7x5 = 35 u |
Change |
- ? |
|
After |
3x7 = 21 u |
5x7 = 35 u |
(a)
The number of chikoos remains unchanged. Make the number of chikoos the same. LCM of 7 and 5 is 35.
35 u = 315
1 u = 315 ÷ 35 = 9
Number of mangoes that the stallholder had at first
= 40 u
= 40 x 9
= 360
(b)
Number of chikoos that the stallholder had to sell to have an equal number of mangoes and chikoos
= 35 u - 21 u
= 14 u
= 14 x 9
= 126
Answer(s): (a) 360; (b) 126
