(d) 12,400​

Answer 1

Solution:

Let A = Income of A

B = Income of B

C = Income of C

Then,

A = 3B ___(1)

B = 2C ___(2)

Here, given that C = 2000.

→ B = 2C = 2×2000 = 4000

→ A = 3B = 3×4000 = 12000

Income of

A is 12000

B is 4000

C is 2000

Conclusion:

Total Income of A, B and C

= 12000 + 2000 + 4000

= 18000 (c)
