The total weight of 12 boys and 8 girls is 1080 kg. If the average weight of boys is 50 kg, then what will be average weight of girls?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 60 kg

Let the average weight of Girls be x.

Average = sum of all weight/total number of persons

A/c to question,

1080 = Weight of Boys + Weight of girls.

1080 = (12 × 50) + (8 × x)

1080 = 600 + 8x

480 = 8x

x = 60Kg.

Hence The average weight of Girls is 60kg.
