Q26 2024, Percentage

P’s salary is 20% lower than Q’s salary which is 20% lower than R’s salary. By how much percent is R’s salary more than P’s salary?

P का वेतन Q के वेतन से 20% कम है जो R के वेतन से 20% कम है। R का वेतन, P के वेतन से कितने प्रतिशत अधिक है?

Explanation Please wait..

Let's assume R's salary is 100 units.
Q's salary is 20% lower than R's, which is 100- (20% × 100) = 100-20 = 80 units.
P's salary is 20% lower than Q's, which is 80- (20% × 80) = 80-16 = 64 units.
Now, we need to find out by what percent R's salary is more than P's salary:

Percent Increase = (Increase in Salary /Original Salary of P ) × 100
Increase in Salary = R's Salary - P's Salary = 100-64 =36
Percent Increase = (36/64) × 100 = 56.25%

So, the correct answer is (b) 56.25%.
