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?

[A].

3 : 3 : 10

[B].

10 : 11 : 20

[C].

23 : 33 : 60

[D].

Cannot be determined

Answer: Option C

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

Answer: Option B

Explanation:

A : B = 200 : 169.

A : C = 200 : 182.

C = C x A = 182 x 200 = 182 : 169.
B A B 200 169

When C covers 182 m, B covers 169 m.

When C covers 350 m, B covers 169 x 350 m = 325 m.
182

Therefore, C beats B by (350 – 325) m = 25 m.
