Question
The average price of two cars, namely 'M' and 'N' is Rs.
45,000 whereas the average price of cars 'N' and 'O' is Rs. 50,000. If the average price of car 'M' and 'O' is Rs. 47,500, then find the price of car 'O'.Solution
ATQ, Let the price of car ‘M’, ‘N’ and ‘O’ be Rs. ‘p’, Rs. ‘q’ and Rs. ‘r’, respectively. p + q = 90,000 q + r = 1,00,000 r + p = 95,000 So, 2(p + q + r) = 2,85,000 Or, p + q + r = 1,42,500 So, price of car ‘r’ = 1,42,500 – 90,000 = Rs. 52,500
