1. Three families A, B and C share 480kg of rice. B gets twice as much as A and C gets half as much as B. How much does each family gets?
Answers
Answer:
Rice family A get = 120 kg
Rice family B get= 240 kg
Rice Family C get = 120 kg
Step-by-step explanation:
let the family A get rice be x
then the family B get rice =2x( as it get twice than Family A)
Family C get rice be x (as it get rice half of family B)
total quantity of rice= 480 kh
then the equation will be
Family A rice+ Family B rice + Family C rice= total quantity of rice
x+2x+x=480
4x=480÷4
x=120
Family A get = x= 120 kg rice
Family B get= 2x=2×120 =240 kg rice
Family C get =x= 120 kg rice

Given:-
- Total rice shared by families A, B and C = 480kg
- Let the amount of rice family A gets be 'r'.
Now Acc. To Que.
- Family B gets 2r kg of rice.
- Family C gets 1/2×2r kg of rice = r kg.
Also,
=》A + B + C = 480 kg.
=》r + 2r + r = 480 kg.
=》 4r = 480 kg.
=》 r = 480 kg/4.
=》 r = 120 kg.
Therefore Family A gets 120 kg of rice.
Family B gets 2 ×120 = 240 kg of rice.
Family C gets 1/2×240 kg = 120 kg.
