There was an equal number of pomegranates and pears. On Wednesday, some pomegranates were added, such that the number of pomegranates increased by 60%. On Thursday, the number of pomegranates further increased by 50% and the number of pears decreased by 30%. There were 153 more pomegranates than pears in the end. How many pomegranates and pears were there altogether at first?

	Pomegranates	Pears
Before	1 u	1 u
Change 1	+ 0.6 u	No change
After 1	1.6 u	1 u
Change 2	+ 0.8 u	- 0.3 u
After 2	2.4 u	0.7 u

Number of pomegranates added on Wednesday
= 60% x 1 u
= ⁶⁰₁₀₀ x 1 u
= 0.6 u

Number of pomegranates increased on Thursday
= 50% x 1.6 u
= ⁵⁰₁₀₀ x 1.6 u
= 0.8 u

Number of pears decreased on Thursday
= 30% x 1 u
= ³⁰₁₀₀ x 1 u
= 0.3 u

Number of more pomegranates than pears in the end
= 2.4 u - 0.7 u
= 1.7 u

1.7 u = 153

1 u = 153 ÷ 1.7 = 90

Total number of pomegranates and pears at first
= 1 u + 1 u
= 2 u
= 2 x 90
= 180

Answer(s): 180
