Answer:
60 years is the answer
Step-by-step explanation:
The average age of 8 men is increased by 2 years. So, the increase in the sum of ALL their ages is 8x2 = 16 years. The 20 and 24 years olds reduce the total by 20+24 = 44 years. So, the new comers need to replace the 44 and add 16 years; i.e. they need to bring in a total of 44+16 = 60 years.
