If Amina’s salary is 60% more than Bina’s salary, then Bina’s salary is what percent less than Amina’s salary?

Question: If Amina’s salary is 60% more than Bina’s salary, then Bina’s salary is what percent less than Amina’s salary?

Solution:
Let,
Bina’s Salary is Tk. 100. Then,
Amina’s Salary = (100 + 60% of 100)
= 100 + (60× 100)/100
= 100 + 60
= 160

Difference between Amina’s Salary and Bina’s Salary = 160 - 100 = 60

∴ lower = (60/160) × 100 = 37.5%

∴ Bina’s salary is 37.5% lower than Amina’s salary.
