Question

The salaries A, B, C are in the ratio 2 : 3 : 5. If the increments of 15%, 10% and 20% are allowed respectively in their salaries, then what will be new ratio of their salaries?

Answer 1

Let salary of
A = 2k,
B = 3k,
C = 5k

=>A's new salary = 115/100 of 2k = 115/100 x 2k = 23k/13

=>B's new salary = 110/100 of 3k = 110/100 x 3k = 33k/10

=>C's new salary = 120/100 of 5k = 120/100 x 5k = 6k

Hence,new ratio = 23k/13 : 33k/10 : 6k = 23 : 33 : 60

Answer 2

The salaries A, B, C are in the ratio 2 : 3 : 5.

Let A = 2x

B = 3x

C = 5x

A's new salary = (100+15%) of 2x

→ = 115/100×2x

→ = 23x/10

B's new salary= (100+10%) of 3x

→ = 110/100 ×3x

→ = 33x/10

C's new salary = (100+20%) of 5x

→ = 120/100×5x

→ = 60x/100

Ratio of their new salaries = (23x/10 : 33x/10 : 60x/10)

→ (23:33:60)

Hope it helps
