Question

The average weight of a group of 4 boys and 6 girls is 64 kg. The average weight of the boys is 70 kg. What is the average weight of the girls?

Answer 1

Answer:

60 Kg

Step-by-step explanation:

4g+6b=10 children

avg= 64 kg

so total is 64*10=640 kg

4 boys' avg wt is 70kg

total wt of 4 boys=70*4

=280 kg

subtract this from 640

we get

360 which is total wt of 6 girls

so avg wt of girls is

360/6

=60 kg ANSWER
