A’s and B’s salaries are respectively 40% and 70% rupees more than C’s salary. What is the ratio of B’s salary to A’s salary?

Correct option is A

Given:
Let C’s salary = 100
A’s salary is 40% more than C’s salary.
B’s salary is 70% more than C’s salary.
Formula Used:
New Value = Original Value × (1 + Increase% / 100)
Solution:
C’s salary = 100
A’s salary
= 100 × (1 + $$\frac{40}{100}$$​)
= 100 × $$\frac{140}{100}$$​
= 140
B’s salary
= 100 × (1 + $$\frac{70}{100}$$​)
= 100 × $$\frac{170}{100}$$​
= 170
Required ratio (B : A)
= 170 : 140
= 17 : 14
