Answer:
Weight of a pile of sand = 90 Kg
Ratio of weight of sand in three bags =
2 : 3 : 7
Let the weights be 2x kg, 3x kg and 7x kg respectively
A.T.Q.
=> 2x + 3x + 7x = 90
=> 12x = 90
=> x = 90/12
=> x = 7.5 Kg

Weight of sand in small bag =
=> 2 × 7.5
=> 15 Kg ANS
Weight of sand in medium bag =
=> 3 × 7.5
=> 22.5 Kg ANS
Weight of sand in large bag =
=> 7 × 7.5

Answer:
15 kg, 22.5 kg and 52.5 kg
Step-by-step explanation:
Ratio of weights of the bags: 2:3:7 and total is 90 kg, let's show this as equation:
- 2x+3x+7x=90
- 12x=90
- x=90/12
- x=7.5 kg
2x=2*7.5 kg= 15 kg
3x= 3*7.5 kg= 22.5 kg
7x= 7* 7.5 kg= 52.5 kg
