There was an equal number of mangoes and lemons. On Friday, some mangoes were added, such that the number of mangoes increased by 80%. On Saturday, the number of mangoes further increased by 50% and the number of lemons decreased by 20%. There were 114 more mangoes than lemons in the end. How many mangoes and lemons were there altogether at first?

	Mangoes	Lemons
Before	1 u	1 u
Change 1	+ 0.8 u	No change
After 1	1.8 u	1 u
Change 2	+ 0.9 u	- 0.2 u
After 2	2.7 u	0.8 u

Number of mangoes added on Friday
= 80% x 1 u
= ⁸⁰₁₀₀ x 1 u
= 0.8 u

Number of mangoes increased on Saturday
= 50% x 1.8 u
= ⁵⁰₁₀₀ x 1.8 u
= 0.9 u

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

Number of more mangoes than lemons in the end
= 2.7 u - 0.8 u
= 1.9 u

1.9 u = 114

1 u = 114 ÷ 1.9 = 60

Total number of mangoes and lemons at first
= 1 u + 1 u
= 2 u
= 2 x 60
= 120

Answer(s): 120
