Question

10 girls have their average age 14 years and 12 boys have their average age as 16 years.

When 6 boys from these 12 join the 10 girls, they all together have average age as 14.5 years.

What is the average age of the remaining 6 boys?​

Answer 1

Answer:

16.66

Step-by-step explanation:

10 girls total age = 10*14=140

12 boys total age = 12*16=192

Total age of girls and boys is 140+192=332

when 6 boys joined the girls the total age will be = 16*14.5=232

by substracting this new age from total age gives remaining 6 boys age

332-232=100

average is 100/6=16.66
