If Ali’s salary is 10% more than that of Sajjad’s, then how much percent is Sajjad’s salary is less than that of Ali?

🧠 Explanation (Math):

Given: Ali’s salary = 10% more than Sajjad’s
Step 1: Let Sajjad = S ⇒ Ali = 1.10S
Step 2: % by which Sajjad is less than Ali = (Ali − Sajjad)/Ali × 100
Step 3: = (0.10S)/(1.10S) × 100 = (1/11) × 100 = 100/11%
Final Answer: 100/11
