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.
