During a recent club trip to the seaside, I sat at the rear of the bus.
I noticed a strange thing: Ann, Kevin, Matilda, and Nathaniel were all sitting on the left side of the bus.
Even more curious was the fact that Jack, Amelia, Isabella, and Maximilian were all sitting on the right side of the bus.
On which side was James sitting?

Hint
A little algebra might help.
Answer
Pineapple = 83p, coconut = 57p, melon = 62p.
Reasoning
If we assign the letters P, C and M to the fruits, and work in pence we have:
(1) M + C = 119
(2) M + P = 145
(3) C + P = 140
Using (2) − (1) we have:
(4) P − C = 26
And (3) + (4) gives:
2P = 166
P = 83
This can then be substituted back into (2) and (3).
