Question

30% of A’s salary is equal to 20% of \(\frac{3}{5}\)^th of B’s salary. If B’s salary is Rs. 2,400, then what is A’s salary ?
1. None of these
2. Rs. 1010
3. Rs. 960
4. Rs. 2060

Answer 1

Correct Answer - Option 3 : Rs. 960

Given:

30% of A's salary = 20% of 3/5th of B's salary 

B's salary = Rs.2400 

Calculation:

As per the question:

30/100 × A = 20/100 × 3/5 × B 

⇒ 30A = 12B

⇒ A/B = 12/30 

⇒ A/B = 2/5 

Let the salary of A and B be 2a and 5a respectively. 

So, B's salary = Rs.2400 

⇒ 5a = Rs.2400 

⇒ a = Rs.480 

∴ A's salary = 2a = 2 × Rs.480 

⇒ Rs.960
