There was an equal number of mangoes and pomegranates. On Monday, some mangoes were added, such that the number of mangoes increased by 60%. On Tuesday, the number of mangoes further increased by 50% and the number of pomegranates decreased by 20%. There were 64 more mangoes than pomegranates in the end. How many mangoes and pomegranates were there altogether at first?

	Mangoes	Pomegranates
Before	1 u	1 u
Change 1	+ 0.6 u	No change
After 1	1.6 u	1 u
Change 2	+ 0.8 u	- 0.2 u
After 2	2.4 u	0.8 u

Number of mangoes added on Monday
= 60% x 1 u
= ⁶⁰₁₀₀ x 1 u
= 0.6 u

Number of mangoes increased on Tuesday
= 50% x 1.6 u
= ⁵⁰₁₀₀ x 1.6 u
= 0.8 u

Number of pomegranates decreased on Tuesday
= 20% x 1 u
= ²⁰₁₀₀ x 1 u
= 0.2 u

Number of more mangoes than pomegranates in the end
= 2.4 u - 0.8 u
= 1.6 u

1.6 u = 64

1 u = 64 ÷ 1.6 = 40

Total number of mangoes and pomegranates at first
= 1 u + 1 u
= 2 u
= 2 x 40
= 80

Answer(s): 80
