I want to know grams for specific price. I have added a question below.


250 grams sugar is 37 rupees.
A person wants to buy sugar for 8 rupees. So how much grams would be for 8 rupees?

Could anybody help me to find the answer?
 
You know you can buy 250 grams for 27 rupees. So you can buy \(\displaystyle \frac{250}{27}\) grams for one rupee. And from that you can buy \(\displaystyle 8\left(\frac{250}{27}\right)= \left(\frac{2000}{27}\right)\) grams for 8 rupees.
 
250 grams ------> 37 rupees

divide both sides by 37 so you can get for 1 rupee.
(250 grams) / (37) --------> 1 rupee

multiply on both sides by 8 as in question it is required to buy sugar for 8 rupees (If it is 10 rupees multiply by 10).
((250g)/37)*8 ------------> 8 rupees

for 8 Rupees it is 54 grams
