• B. Rs. 2625
• C. Rs. 3025
• D. Rs. 2825
• E. None of these

Answer 1

The correct option is A Rs. 2425

Average salary of 9 persons = Rs. 2450
Total salary of 9 persons
$=Rs.2450\times 9=Rs.2650$
Total salary of the person who is transferred = Rs. 2650
Thus, the total salary of remaining 8 persons
= Rs. 22050 - Rs. 2650 = Rs. 19400
The average salary of the remaining 8 persons
$=Rs.\frac{19400}{8}=Rs.2425.$
