There was an equal number of pomegranates and passion fruits. On Tuesday, some pomegranates were added, such that the number of pomegranates increased by 80%. On Wednesday, the number of pomegranates further increased by 50% and the number of passion fruits decreased by 10%. There were 36 more pomegranates than passion fruits in the end. How many pomegranates and passion fruits were there altogether at first?

	Pomegranates	Passion Fruits
Before	1 u	1 u
Change 1	+ 0.8 u	No change
After 1	1.8 u	1 u
Change 2	+ 0.9 u	- 0.1 u
After 2	2.7 u	0.9 u

Number of pomegranates added on Tuesday
= 80% x 1 u
= ⁸⁰₁₀₀ x 1 u
= 0.8 u

Number of pomegranates increased on Wednesday
= 50% x 1.8 u
= ⁵⁰₁₀₀ x 1.8 u
= 0.9 u

Number of passion fruits decreased on Wednesday
= 10% x 1 u
= ¹⁰₁₀₀ x 1 u
= 0.1 u

Number of more pomegranates than passion fruits in the end
= 2.7 u - 0.9 u
= 1.8 u

1.8 u = 36

1 u = 36 ÷ 1.8 = 20

Total number of pomegranates and passion fruits at first
= 1 u + 1 u
= 2 u
= 2 x 20
= 40

Answer(s): 40
