1.	The cost of 3 ,3 by 4 kg of sugar is 121 one by two rupees find it cost per 1kg
Answer» Answer: 3 1/2 kg of sugar COSTS 63 RUPEES 3 1/2 kg = 7/2 kg We WANT to find out how much 1 3/4 kg of sugar costs. Let's call this amount x. 1 3/4 kg = 7/4 kg We can form an equation of proportions: (7/4 kg) / (7/2 kg) = (x rupees)/(63 rupees) (7/4) / (7/2) = (7/4)*(2/7) = 1/2 So, 1/2 = x/63 This yields x = 63/2 = 31.5 rupees through CROSS multiplication So, 1 3/4 kg of sugar costs 31.5 rupees.

Answer»

Answer:

3 1/2 kg of sugar COSTS 63 RUPEES

3 1/2 kg = 7/2 kg

We WANT to find out how much 1 3/4 kg of sugar costs. Let's call this amount x.

1 3/4 kg = 7/4 kg

We can form an equation of proportions:

(7/4 kg) / (7/2 kg) = (x rupees)/(63 rupees)

(7/4) / (7/2) = (7/4)*(2/7) = 1/2

So, 1/2 = x/63

This yields

x = 63/2 = 31.5 rupees through CROSS multiplication

So, 1 3/4 kg of sugar costs 31.5 rupees.
