Question
The average salary of A, B and C is Rs. 22000
while average salary of B, C and D is Rs. 25000. If the average salary of D be 2 times of that of A, then the average salary of B and C is:Solution
A + B + C = 22000 * 3 = 66000 B + C + D = 25000 * 3 = 75000 D - A = 75000 - 66000 = 9000 D = 2 A => A = 9000/1 = 9000 So, D = 9000 * 2 = 18000 Average salary of B and C = (75000 - 18000)/2 = 28500
