30 x 70 = 2100
20 x 40 = 800
2100 / 50 ( because there are 30 males and 20 females ) = 58

To find the average age of the entire group, we need to calculate the total combined age of all individuals and then divide by the total number of individuals.
Total combined age of males = 30 males * 70 years = 2100 years Total combined age of females = 20 females * 40 years = 800 years
Total combined age of the entire group = 2100 + 800 = 2900 years
Total number of individuals = 30 males + 20 females = 50 individuals
Average age of the group = 2900 years / 50 individuals = 58 years
