In an office, there are 18 employees. The average age of all the employees is 28 years. If the age of three senior managers is included, then the average age is increased by 2 years. Find the average age of three senior managers.
ATQ, Average age of 18 employees = 28 years Sum of the ages of 18 employees = 28 × 18 = 504 After including the age of 3 senior managers, new average age = 30 years Sum of the ages of 18 employees including senior managers = 30 × 21 = 630 Sum of the ages of 3 senior managers = 630 – 504 = 126 Average age of 3 senior managers = 126/3 = 42 years
24.99 × 32.05 + ? - 27.01 × 19.97 = 29.99 × 27.98
25.11 × 3.98 + 26.03 × 4.12 – 33.95 + 94.9 × 4.02 =?
320.98 + 49.99% of (261.09 + 138.98) = ?
8.992 + (5.01 × 4.98) + ? = 224.03
24.96% of 380 + ? – 169.99 = 149.99% of 80
3.98 × 29.67 ÷ 11.90 of √24.89 = ?% of 199.79
?% of 399.97 = 11.982 + 16.13 × 4.16 – 35.99
?% of [(12.96 × 40.05) + 25.08 × 18.96] = 17.96 × 22.05 + 3.05 × 66.96
1299.99 ÷ 20.21 = ? + 325.985 - (180 ÷ 6 × 24.03)
