Question 131

Last year, 5 companies had an average of 16 non working days each. This year 3 companies had 10 more non working days each, and 2 companies had 5 fewer non working days each. What was the average number of non working days given by the same companies this year ?

Solution

Total number of non working days by 5 companies last year = $$5\times16=80$$

Non working days this year = $$80+(3\times10)-(2\times5)=100$$

=> Required average = $$\frac{100}{5}=20$$
