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
Read Solution (Total 10)
-
- 2 mangoes and 3 oranges weigh 2 kg
multiply by 10.
weight of 20 mangoes and 30 oranges = 2*10 = 20 kg. - 12 years agoHelpfull: Yes(106) No(0)
- 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 - 12 years agoHelpfull: Yes(17) No(2)

- 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)=15kg

- Data sufficiency question
Only ii is sufficient - 8 years agoHelpfull: Yes(2) No(1)
- 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 - 11 years agoHelpfull: Yes(1) No(0)
- 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 - 9 years agoHelpfull: Yes(0) No(0)
- 2 is alone sufficient to answer
