Three hours ago, a fruit seller started his day with some chikoos and lemons in the ratio of 7 : 3. There were 60 lemons. Some of the chikoos were bought by Emily. As a result, the number of chikoos became
34 of the lemons.
- How many chikoos did the fruit seller have left?
- How many chikoos did the fruit seller have to buy in order to have an equal number of chikoos and lemons?

Chikoos |
Lemons |
Before |
7x4 = 28 u |
3x4 = 12 u |
Change |
- ? |
|
After |
3x3 = 9 u |
4x3 = 12 u |
(a)
The number of lemons remains unchanged. Make the number of lemons the same. LCM of 3 and 4 is 12.
12 u = 60
1 u = 60 ÷ 12 = 5
Number of chikoos that the fruit seller had left
= 9 u
= 9 x 5
= 45
(b)
Number of chikoos that the fruit seller had to buy to have an equal number of chikoos and lemons
= 12 u - 9 u
= 3 u
= 3 x 5
= 15
Answer(s): (a) 45; (b) 15
