How much is the weight of 20 mangoes and 30 oranges?
i. 1 orange weighs twice that of 1 mango
ii. 2 mangoes and 3 oranges weigh 2 kg

• 2 mangoes and 3 oranges weigh 2 kg
  
  multiply by 10.
  weight of 20 mangoes and 30 oranges = 2*10 = 20 kg.

• consider mangoes = x and oranges = y
  so weight of 20x and 30y need to find
  1y=2x from i
  2x+3y=2 from ii
  solving two we get x=1/4,y=1/2
  we get weight of 20x(20 mangoes) = 20*(1/4) = 5
  we get weight of 30y(30 oranges) = 30*(1/2) = 15

• let weight of 1 mango be x
  and weight of 1 orange be 2x
  then weight of 2mangoes =2x
  weight of 3 oranges=3*2x=6x
  2x + 6x=2
  8x=2
  x=0.25=weight of 1 mango
  2x=2*0.25=0.5=weight of 1 orange
  weight of 20 mangoes and 30 oranges=(20*0.25) + (30*0.5)=20kg

• Given:
  R-orange; M-mango
  R=2M
  2M+3R=2
  On solving,
  1M=1/4 1R=1/2
  Therefore, 20 M+ 30R=5+15=Rs.20

• 1. if 1 mango weights 1 kg then each orange weights 2 kg . total mangoes weight 1*20=20 kgs . and total weight of oranges is 2*30=60 kgs .Total weight is 20+60=80 kgs
  2. if 2 mangoes weights 2 kg then 20 mangoes weights 10 kg. if 3 oranges weights 2 kg then 30 oranges weights 20 kg.Total weight of mangoes & oranges is 10+20=30 kgs
