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.
