There was an equal number of passion fruits and peaches. On Monday, some passion fruits were added, such that the number of passion fruits increased by 60%. On Tuesday, the number of passion fruits further increased by 50% and the number of peaches decreased by 10%. There were 150 more passion fruits than peaches in the end. How many passion fruits and peaches were there altogether at first?

	Passion Fruits	Peaches
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 passion fruits added on Monday
= 60% x 1 u
= ⁶⁰₁₀₀ x 1 u
= 0.6 u

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

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

Number of more passion fruits than peaches in the end
= 2.4 u - 0.9 u
= 1.5 u

1.5 u = 150

1 u = 150 ÷ 1.5 = 100

Total number of passion fruits and peaches at first
= 1 u + 1 u
= 2 u
= 2 x 100
= 200

Answer(s): 200
