If the average price of three chairs is ₹14,014 and their prices are in the ratio of 3 : 4: 7, then the highest price (in ₹) of chair is:

3,003 21,021 7,007 5,005

21,021

Ratio of prices = 3 : 4 : 7  Total = 14r Average = $\frac{14r}{3}$ = 14014 Thus, 14r = 14014 x 3              r = 1001 x 3 = 3003 Highest price  = 7r = 7 x 3003 = 21021
