Solution :-
Average age of senior citizens = 62 years
Total age of 2 senior citizens = 62*2 = 124 years
Average age of adults = 32 years
Total age of 2 adults = 32*2 = 64 years
Average age of the children = 9 years.
Total age of 4 children = 9*4 = 36 years
Total age of 2 senior citizens, 2 adults and 4 children = 124 + 64 + 36
= 224 years
Average age of the 8 travellers in the car = 224/8
= 28 years
Answer.
Average age of senior citizens = 62 years
Total age of 2 senior citizens = 62*2 = 124 years
Average age of adults = 32 years
Total age of 2 adults = 32*2 = 64 years
Average age of the children = 9 years.
Total age of 4 children = 9*4 = 36 years
Total age of 2 senior citizens, 2 adults and 4 children = 124 + 64 + 36
= 224 years
Average age of the 8 travellers in the car = 224/8
= 28 years
