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?
3 : 3 : 10
10 : 11 : 20
23 : 33 : 60
Cannot be determined
Answer: Option
Explanation:

Let A = 2k, B = 3k and C = 5k.

A's new salary = 115 of 2k = 115 x 2k = 23k
100 100 10

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

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

New ratio 23k : 33k : 6k = 23 : 33 : 60
10 10

Simplest way to understand.

15% increment in A Salary, So,
2*15% = 0.3.

Total Salary of A after increment = 2+0.3 = 2.3.

10% increment in B Salary, So,
3*10% = 0.3.

Total Salary of B after increment = 3+0.3 = 3.3.

20% Increment in C Salary, So,
5*20% = 1.

Total Salary of C after increment = 5+1 = 6.

Ratio of salary of A, B & C after increment.

2.3 : 3.3 : 6.0.

So 23 : 33 : 60 Answer.

Let's salaries A,B,C are 200:300:500 i.e 2:3:5.

A-increase of 15% is 200+30 = 230.
B-increase of 10% is 300+33 = 330.

C-increase of 20%b is 500+100 = 600.
Ratio of A:B:C is 230: 330: 600.

i.e 23: 33: 60.

Why is that the amount of % is written as 115 instead of 15 ?
