Question
Meera buys a laptop and sells it to Sneha at a profit of
25%. Sneha then sells it to Tushar at a loss of 10%. If Tushar buys the laptop for Rs. 36,450, find the price at which Sneha bought the laptop.Solution
ATQ, Let the cost price of the laptop for Meera be Rs. '100y'. Cost price of the laptop for Sneha = 1.25 × 100y = Rs. '125y' Cost price of the laptop for Tushar = 125y × 0.90 = Rs. '112.5y' ATQ, 112.5y = 36,450 So, y = (36450/112.5) = 324 Therefore, the price at which Sneha bought the laptop = 125y = 125 × 324 = Rs.40,500.
