Question

A man buys spirit at ₹ 60 per litre, adds water to it and then sells it at ₹ 75 per litre. What is the ratio of spirit to water if his profit in the deal is 37.5%?

पर्याय

• 9 : 1

• 10 : 1

• 11 : 1

• None of these

Answer 1

10 : 1

Explanation:

S.P. per litre = ₹ 75

C.P. per litre of the mixture = `75 xx 100/137.5 = 600/11`

C.P. per litre of spirit and water is ₹ 60 and zero respectively.

Ratio of water to spirit = 60 : 600 = 1 : 10

So, required ratio = 10 : 1 .....(Sprit to water)
