In a school, the average salary of 12 teachers was ₹71,400. If the average salary of the teachers, principal and vice principal was ₹89,500, then what was the average salary of the principal and vice principal (in ₹)?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e 1,98,100.
Total salary of 12 teachers = 12 × 71,400 = 8,56,800
Total salary of 14 persons (12 teachers + principal + vice principal) = 14 × 89,500 =
12,53,000
Salary of principal + vice principal = 12,53,000 – 8,56,800 = 3,96,200
Average salary of principal and vice principal = 3,96,200 ÷ 2 = 1,98,100
