Q.  5 % income of a is equal to 15 % income of B and 10 % income of B is equal to 20 % income of C if the income of c is Rs. 200, then total income of A, B and C is :_________?

a. Rs. 6000
b. Rs. 18000
c. Rs. 20000
d. Rs. 14000


ANSWER: See Answer
 
5 % A = 15 % B and 10 % B = 20 % C.

A/20 = 3B/20 and B/10 = C/5

or B = 2C. A/20 = 3/20 × 2c = 3/10

C = 3/10 × 2000 = 600

A = (600 × 20) = 12000,

B = (2 × 2000) = 4000

A + B + C = (12000 + 4000 + 2000) = 18000

Therefore, Rs. 18000/-
