There was an equal number of chikoos and lemons. On Friday, some chikoos were added, such that the number of chikoos increased by 80%. On Saturday, the number of chikoos further increased by 50% and the number of lemons decreased by 20%. There were 152 more chikoos than lemons in the end. How many chikoos and lemons were there altogether at first?

	Chikoos	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 chikoos added on Friday
= 80% x 1 u
= ⁸⁰₁₀₀ x 1 u
= 0.8 u

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

1.9 u = 152

1 u = 152 ÷ 1.9 = 80

Total number of chikoos and lemons at first
= 1 u + 1 u
= 2 u
= 2 x 80
= 160

Answer(s): 160
