There was an equal number of lemons and passion fruits. On Saturday, some lemons were added, such that the number of lemons increased by 60%. On Sunday, the number of lemons further increased by 50% and the number of passion fruits decreased by 30%. There were 68 more lemons than passion fruits in the end. How many lemons and passion fruits were there altogether at first?

	Lemons	Passion Fruits
Before	1 u	1 u
Change 1	+ 0.6 u	No change
After 1	1.6 u	1 u
Change 2	+ 0.8 u	- 0.3 u
After 2	2.4 u	0.7 u

Number of lemons added on Saturday
= 60% x 1 u
= ⁶⁰₁₀₀ x 1 u
= 0.6 u

Number of lemons increased on Sunday
= 50% x 1.6 u
= ⁵⁰₁₀₀ x 1.6 u
= 0.8 u

Number of passion fruits decreased on Sunday
= 30% x 1 u
= ³⁰₁₀₀ x 1 u
= 0.3 u

Number of more lemons than passion fruits in the end
= 2.4 u - 0.7 u
= 1.7 u

1.7 u = 68

1 u = 68 ÷ 1.7 = 40

Total number of lemons and passion fruits at first
= 1 u + 1 u
= 2 u
= 2 x 40
= 80

Answer(s): 80
