Harry had to collect some fruits from two shops and deliver some fruits to another shop. He collected from Shop P and the ratio of passion fruits to oranges was 1 : 3. When he reached Shop Q, he unloaded
1112 of the oranges and some passion fruits from his vehicle. The ratio of passion fruits to oranges became 1 : 2. At Shop R, 32 passion fruits and 16 oranges were collected and the number of passion fruits to oranges became the same.

Comparing passion fruits and oranges at first |
Shop P |
1x8 = 8 u |
3x8 = 24 u |
Before 1 |
Shop P |
8 u |
12x2 = 24 u |
Change 1 |
Shop Q |
- ? |
- 11x2 = - 22 u |
After 1 |
Shop R |
1 u |
1x2 = 2 u |
Before 2 |
Shop R |
1x1 = 1 u |
2x1 = 2 u |
Change 2 |
Shop R |
+ 32 |
+ 16 |
After 2 |
Shop R |
1 u + 32 |
2 u + 16 |
(a)
The number of oranges after unloading at Shop Q is repeated. Make the number of oranges left after unloading at Shop Q the same. LCM of 2 and 1 is 2.
The number of oranges collected at Shop P is repeated. Make the number of oranges collected at Shop P the same by multiplying 3 by 8.
The number of passion fruits and oranges in the end is the same.
2 u + 16 = 1 u + 32
2 u - 1 u = 32 - 16
1 u = 16
Number of passion fruits on his vehicle after collecting from Shop R
= 1 u + 32
= 1 x 16 + 32
= 16 + 32
= 48
Number of fruits on his vehicle after collecting from Shop R
= 2 x 48
= 96
(b)
Number of passion fruits delivered to Shop Q
= 8 u - 1 u
= 7 u
= 7 x 16
= 112
Answer(s): (a) 96; (b) 112
