• A. Rs.$19,850$
• B. Rs.$20,050$
• C. Rs. $20,250$
• D. Rs. $20,450$

Answer 1

The correct option is A Rs.$19,850$

Average salary of $15$ employees = Rs $9450$
Sum of the salaries of 15 employees = $15\times 9450$ = $141750$
New average after adding salary of supervisor = $9450+650$ = $10100$
Sum of salaries of 16 employees = $10100\times 16$ = $1616600$
Let the salary of the supervisor = $x$
Thus. $x+141750=161600$
$x=19,850$
