There was an equal number of dragonfruits and kiwis. On Monday, some dragonfruits were added, such that the number of dragonfruits increased by 60%. On Tuesday, the number of dragonfruits further increased by 50% and the number of kiwis decreased by 10%. There were 75 more dragonfruits than kiwis in the end. How many dragonfruits and kiwis were there altogether at first?

	Dragonfruits	Kiwis
Before	1 u	1 u
Change 1	+ 0.6 u	No change
After 1	1.6 u	1 u
Change 2	+ 0.8 u	- 0.1 u
After 2	2.4 u	0.9 u

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

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

Number of kiwis decreased on Tuesday
= 10% x 1 u
= ¹⁰₁₀₀ x 1 u
= 0.1 u

Number of more dragonfruits than kiwis in the end
= 2.4 u - 0.9 u
= 1.5 u

1.5 u = 75

1 u = 75 ÷ 1.5 = 50

Total number of dragonfruits and kiwis at first
= 1 u + 1 u
= 2 u
= 2 x 50
= 100

Answer(s): 100
