Dylan had to collect some fruits from two stalls and deliver some fruits to another stall. He collected from Stall V and the ratio of mangoes to lemons was 3 : 4. When he reached Stall W, he unloaded
78 of the lemons and some mangoes from his vehicle. The ratio of mangoes to lemons became 2 : 3. At Stall X, 53 mangoes and 50 lemons were collected and the number of mangoes to lemons became the same.

- How many mangoes were delivered to Stall W?

Comparing mangoes and lemons at first |
Stall V |
3x6 = 18 u |
4x6 = 24 u |
Before 1 |
Stall V |
18 u |
8x3 = 24 u |
Change 1 |
Stall W |
- ? |
- 7x3 = - 21 u |
After 1 |
Stall X |
2 u |
1x3 = 3 u |
Before 2 |
Stall X |
2x1 = 2 u |
3x1 = 3 u |
Change 2 |
Stall X |
+ 53 |
+ 50 |
After 2 |
Stall X |
2 u + 53 |
3 u + 50 |
(a)
The number of lemons after unloading at Stall W is repeated. Make the number of lemons left after unloading at Stall W the same. LCM of 3 and 1 is 3.
The number of lemons collected at Stall V is repeated. Make the number of lemons collected at Stall V the same by multiplying 4 by 6.
The number of mangoes and lemons in the end is the same.
3 u + 50 = 2 u + 53
3 u - 2 u = 53 - 50
1 u = 3
Number of mangoes on his vehicle after collecting from Stall X
= 2 u + 53
= 2 x 3 + 53
= 6 + 53
= 59
Number of fruits on his vehicle after collecting from Stall X
= 2 x 59
= 118
(b)
Number of mangoes delivered to Stall W
= 18 u - 2 u
= 16 u
= 16 x 3
= 48
Answer(s): (a) 118; (b) 48
