Question
The average price of two books, namely 'X' and 'Y' is
Rs. 850 whereas the average price of books 'Y' and 'Z' is Rs. 910. If the average price of book 'X' and 'Z' is Rs. 875, then find the price of book 'Z'.Solution
ATQ, Let the price of book ‘X’, ‘Y’ and ‘Z’ be Rs. ‘p’, Rs. ‘q’ and Rs. ‘r’, respectively. p + q = 1700 q + r = 1820 r + p = 1750 So, 2(p + q + r) = 5270 Or, p + q + r = 2635 So, price of book ‘r’ = 2635 – 1700 = Rs. 935
