A pile of sand had a weight of 60kg. The sand is out into a small bag, a medium bag and a large bag in the ratio 2:3:7
Work out the weight of sand in each bag

Answer is 10:15:35

Step-by-step explanation:

Let the ratio be 2x,3x,7x

then according to question;

2x+3x+7x=60

12x=60

x=5

now put value of x in the ratios

2x=2x5

=10

3x=3x5

=15

7x=7x5

=35

thus,weight of three bags are 10:15:35
