Question

A, b, c along completed a piece of work in 30, 50 and 70 days. The ratio of the salary of each day is 4 : 3 : 2 respectively. If the total income of a is rs. 144, find total income of



b.

Answer 1

Answer:

Step-by-step explanation:

A:B:C  = 4:3:2

total ratio = 4+3+2 = 9

  A amount = rs. 144

(4 /9) x total Income = 144

           Total Income = 144 x (9/4)

                                  =  rs. 324

B amount = (3/9) x 324 = rs. 108

C amount = (2/9) x 324 =  rs. 72

Answer 2

Answer:

Total income of b is Rs. 180.

Step-by-step explanation:

The ratio of salary of each day = 4:3:2

Suppose the common factor is x

• So, a gets per day 4x /-

            He earns in 30 days = 4x X 30 = 120x

             Now 120x = 144

              x = 144/120 = 1.2

• b's salary per day = 3x = 3 X 1.2 = 3.6 /-

       For 50 days b earns = 3.6 X 50 = 180 /-

Total income of b is Rs. 180.
