Question
The average salary of 35 employees in a company was

ATQ,
Correct average
= {(35 × 42000) – 54000 + 45000 – 39000 + 36000} / 35
= {1470000 – 54000 + 45000 – 39000 + 36000} / 35
= 1470000 – 54000 = 1416000 + 45000 = 1461000 – 39000 = 1422000 + 36000 = 1458000
Correct average = 1458000 / 35 = ₹41,657.14
