Let the total eggs be x.
Given, the cost price of 3 eggs = 5 i.e 5/3 * x --- (1)
Given, the selling price of 5 eggs = 12 i.e 12/5x --- (2)
Given profit = 143 ---- (3)
On solving (1),(2),(3) we get
Profit = SP - CP
143 = 12x/5 - 5/3x
143 = 36x - 25x/15
= 11/15x
x = 195.
No of eggs he purchased = 195.
Hope this helps!
