Question

The income of A, B, and C are in the ratio 8 : 15 : 12. If their incomes be changed such that the new income of A is 50% increased, 20% increased for B and 25% increase for C. Find the ratio of their new incomes.

Answer 1

Answer:

4 : 6: 5

Step-by-step explanation:

4 : 6 : 5

Step-by-step explanation:

1. Find 50% of 8 and add it to the old ratio to find A new income ratio.

 .50 x 8 =  4

  8 + 4 = 12

2. Find 20% of 15 and add it to the old ratio to find B's new income ratio.

  .20 x 15 = 3

  15 + 3 = 18

3. Find 25% of 12 and add it to the old ratio to find C's new income ratio.

  .25 x 12 = 3

  =12 + 3 = 15

4. New ratio income

 = 12:18:15

5. Simplest form. Divide by 3

  = 4 : 6 : 5
