Answers
Answer:
Step-by-step explanation:Heya !
Here's your 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
=> 52.5 Kg ANS

Answer: Small bag = 15 kg , Medium bag = 22.5 kg , Large bag = 52.5 kg
Step-by-step explanation: Ratio = 2 : 3 : 7
Take sum of ratios = 12
2 : 3 : 7 = Small bag : Medium bag : Large bag
Formula = Ratio/ Sum of ratios x total amount
Just apply this formula to find weight of three bags
Small bag = 2/12 x 90 Medium bag = 3/12 x 90 Large bag = 7/12 x 90
= 15 kg = 22.5 kg = 52.5 kg
