Question

The annual income of Rajiv is Rs. 123720 and of Rahul is 114000. Their joint average monthly income is Rs. = ____​

Answer 1

Answer:

Step-by-step explanation:

Monthly income of -

A+B= 2 x 7760 = 15520---1

B+C = 2 x 10990 = 21980---2

C+ A = 2 × 9070 = 18140 - 3

Adding all the three equations -

2(A+B+C) = 15520+21980+18140

2(A+B+C) = 55460 A+B+C = 55460/2

A+B+C = 27820

Thus, from equation 3 -

B = 27280 18140

B = 9680

Therefore, B's annual salary = 12 × 9680

= 116160

Thus the annual income of b is = Rs. 116160
