There was an equal number of kiwis and mangoes. On Friday, some kiwis were added, such that the number of kiwis increased by 60%. On Saturday, the number of kiwis further increased by 50% and the number of mangoes decreased by 20%. There were 32 more kiwis than mangoes in the end. How many kiwis and mangoes were there altogether at first?

	Kiwis	Mangoes
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 kiwis added on Friday
= 60% x 1 u
= ⁶⁰₁₀₀ x 1 u
= 0.6 u

Number of kiwis increased on Saturday
= 50% x 1.6 u
= ⁵⁰₁₀₀ x 1.6 u
= 0.8 u

Number of mangoes decreased on Saturday
= 20% x 1 u
= ²⁰₁₀₀ x 1 u
= 0.2 u

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

1.6 u = 32

1 u = 32 ÷ 1.6 = 20

Total number of kiwis and mangoes at first
= 1 u + 1 u
= 2 u
= 2 x 20
= 40

Answer(s): 40
