The salaries of P, Q and R are in the ratio 3 ∶ 4 ∶ 6. If R’s salary is ₹15,000 more than that of P, then Q’s salary is:

Correct option is B

Given:

The ratio of salaries of P, Q and R is 3 : 4 : 6

R’s salary more than that of P = ₹15,000

Solution:

Let the salaries of P, Q and R  be $$3x$$​ ,$$4x$$​ and $$6x$$​ respectively

According to question:

​$$6x-3x = 15000$$​​

​$$3x = 15000$$​​

​$$x=5000$$​​

Q’s salary = $$4x =4 \times 5000 = \bf ₹20,000$$
