Option 1: 21
Option 2: 22
Option 3: 23
Option 4: 24
Correct Answer: 21
Solution : Given that the average salary of all the associates in a team is Rs. 16,000. Let the total number of associates be $n$. ⇒ Sum of salary of all the associates = $16000n$ Now, The average salary of 7 senior associates is Rs. 24,000. ⇒ Sum of salary of 7 senior associates = 24,000 × 7 = 1,68,000 Also, the average salary of the rest is Rs. 12,000. Remaining associates = $n-7$ ⇒ Sum of salary of remaining associates = 12000($n-7$) We know that, The sum of the salary of all the associates = the sum of the salary of 7 senior associates + the sum of the salary of the remaining associates ⇒ $16000n=168000+12000(n-7)$ ⇒ $16000n=168000+12000n-84000$ ⇒ $16000n-12000n=84000$ ⇒ $4000n=84000$ ⇒ $n=21$ Hence the correct answer is 21.
