First, we need to find the total age of the 10 men:
Average age * number of men = total age
42 * 10 = 420
Next, we know the average age of 6 of the men is 45, so we can find their total age:
45 * 6 = 270
We also know the ages of 3 of the men, which add up to:
29 + 20 + 35 = 84
To find the age of the 10th man, we can subtract the total age of the 9 men we know about from the total age of all 10 men:
420 - 270 - 84 = 66
Therefore, the age of the tenth man is 66 years old.
The average age of 10 men is 42,if the average of 6 of them is 45,and the ages of three of them are 29,20 and 35. What is the age of the tenth man. Calculate the age of the tenth man in years
