Question
The average salary of 35 employees in a company was
calculated to be ₹42,000. Later it was found that ₹45,000 was entered as ₹54,000, and ₹39,000 was noted instead of ₹36,000. Find the correct average salary.Solution
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
[34.01 × 18.98 – 12 × √576.03 – 198] ÷ 3.95 = ?
