The cost price of fridge A is equal to the selling price
of fridge B. The cost price of fridge B is Rs.500 and the selling price of fridge A is Rs.540. If the profit earned on fridge A is 35%, find the profit or loss percentage on fridge B.Solution
ATQ, Let the cost price of fridge A = x Let the selling price of fridge B = y Given: x = y For fridge A: SP = 540, Profit% = 35% SP = CP Γ (100 + 35)/100 540 = x Γ 135/100 540 = 1.35x x = 540 / 1.35 = 400 So, CP of A = Rs.400 SP of B = y = x = Rs.400 For fridge B: CP = 500, SP = 400 Loss = 500 β 400 = 100 Loss% = (100/500) Γ 100 = 20%
