Answer 1

Step-by-step explanation:

Given Three families, A, B and C, share 480 kg of rice.  B gets twice as much as A and C gets half as  much as B. How much does each family get?

• A,B and C share 480 kg of rice.
• According to question,
• So given B = 2A
• C = 1/2 B
•    = 1/2 x 2 A
• C   = A
• So A + B + C = 480
•   A + 2A + A = 480
•  So 4 A = 480
• A = 480 / 4
• Now A = 120
• B = 2 A  
•     = 2 (120)
• B = 240
• So C = 120

Each family will get 120, 240 and 120
