​

Answer 1

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 2

Answer:

Step-by-step explanation:

Given, the cost of 3½ kg of sugar is Rs. 264.

Cost of 1 kg of sugar = 264÷3½ = 264×2/7 = Rs. (528/7)

Cost of 1½ kg of sugar = (528/7)÷1½ = (528x2)/(7x3) = (176x2)/7 = 352/7 = Rs. 50.29

The cost of 1½ kg of sugar is Rs. 50.29 .

Hope this helps :)
