Flynn had to collect some fruits from two marts and deliver some fruits to another mart. He collected from Mart A and the ratio of lemons to mangoes was 1 : 2. When he reached Mart B, he unloaded ⁹₁₀ of the mangoes and some lemons from his van. The ratio of lemons to mangoes became 1 : 2. At Mart C, 48 lemons and 44 mangoes were collected and the number of lemons to mangoes became the same.

1. How many fruits were there on his van after visiting Mart C?
2. How many lemons were delivered to Mart B?

	Location	Lemons	Mangoes
Comparing lemons and mangoes at first	Mart A	1x10 = 10 u	2x10 = 20 u
Before 1	Mart A	10 u	10x2 = 20 u
Change 1	Mart B	- ?	- 9x2 = - 18 u
After 1	Mart C	1 u	1x2 = 2 u
Before 2	Mart C	1x1 = 1 u	2x1 = 2 u
Change 2	Mart C	+ 48	+ 44
After 2	Mart C	1 u + 48	2 u + 44

(a)
The number of mangoes after unloading at Mart B is repeated.  Make the number of mangoes left after unloading at Mart B the same.  LCM of 2 and 1 is 2.

The number of mangoes collected at Mart A is repeated.  Make the number of mangoes collected at Mart A the same by multiplying 2 by 10. 
 
The number of lemons and mangoes in the end is the same.

2 u + 44 = 1 u + 48
2 u - 1 u = 48 - 44

1 u = 4

Number of lemons on his van after collecting from Mart C
= 1 u + 48
= 1 x 4 + 48
= 4 + 48
= 52

Number of fruits on his van after collecting from Mart C
= 2 x 52 
= 104 

(b)
Number of lemons delivered to Mart B
= 10 u - 1 u
= 9 u
= 9 x 4
= 36

Answer(s): (a) 104; (b) 36
