Question

There are 3 men , 1 buys 100kg iron for $80 , 2nd 310kg for $ 210 and 3rd 5600 kg for $4000 . Who will get more iron for per dollar​

Answer 1

Answer:

Man 2 310kg for 210 dollar

Step-by-step explanation:

man 1 = 100 kg 80$ 1 kg = 80/100 = 0.8$

man 2 = 310kg 210$ 1 kg = 210/310 = 0.6$

man 3 = 5600 kg 4000$ 1kg = 4000/5600= 0.7$

I have rounded off the values

Answer 2

Answer:

1st person

Step-by-step explanation:

We should divide to get the answers :-

1st person spends for 1kg iron - 100 ÷ 80 = $1.25

2nd person spends for 1kg iron - 210 ÷ 100 = $2.1

3rd person spends for 1kg iron - 5600 ÷ 4000 = $1.4

So, 1st person gets more iron for per dollar which is $1.25.

Hope it helps! Thank you!
