In a coffee shop, the following coffee samples are prepared for customers. i. 10 g of sugar added to 100 g of coffee ii. 10 g of sugar added to 200 g of coffee iii. 4 g of sugar added to 200 g of coffee iv. 4 g of sugar added to 100 g of coffee based on the amount of sugar added, which sequence ranks the coffee from the sweetest coffee to the least-sweet coffee?

So solve this we must know the amount of sugar per gram of coffee

i.              10 g sugar /100 g coffee = 0.1 g sugar/ 1 g coffee

ii.            10 g sugar / 200 g coffee = 0.05 g sugar / 1 g coffee

iii.           4 g sugar / 200 g coffee = 0.02 g sugar / 1 g coffee

iv.           4 g sugar / 100 g coffee = 0.04 g sugar / 1 g coffee

So the ranking from sweetest so the least is:

 i, ii, iv, iii

the answer would be a
