Question

x sells an aricle to y at a profit of 20 % and y sells it to z at a profit of 25% . if z pays ₹225 for it ,what did x pay for it

Answer 1

Let the C.P to 'X' be Rs. a
Profit = 20%
S.P = C.P*(100+P)/100 = a*120/100

C.P to Y = a*120/100
Profit = 25%
S.P = C.P*(100+P)/100 = a*120/100 * 125/100 = a*12*5/10*4 = a*3/2
Given: a*3/2 = 225
a/2 = 75
a = 150 Rs.
Hence 'X' paid Rs. 150
Hope it helps.
