Question

- A man buys milk at 85 per liter and dilutes it with
water. He sells the mixture at the same rate and thus
gains 11.11%. Find the quantity of water mixed by
him in every liter of milk.
(a) 0.111 liters (b) 0.909 liters
(c) 0.1 litre
(d) 0.125 liters​

Answer 1

Answer:

Lets assume we have 10 litres of milk and hence it will cost Rs 85 (CP)

Say, x litres of water is added to the mixture and there the final volume becomes (10+x) litres.

Given that he sells the mixture at cost price and gains 11.11% i.e. 1/9.

He sells this at Rs (10+x)*8.5 (SP)& makes a final profit of 1/9 %.

Therefore by equating the values in the formula ( SP/CP-1 = Profit% ) we get x= 1/9= o.111 litre6 years agoHelpfull: Yes(3) No(4)Let 100 litres of milk be there and y litres of water be added.

Cost Price=8.5x100=850

So selling price=850+((850*11.11)/100)=944.35

Now,

Also

Selling price=(100+y)x8.5 , since to 100 litres of milk Y liters of water is added.

Hence,

(100+y)x8.5=944.35

y=11.11

Now in 100 litres 11.11 litres of water is present hence in 1 litre 0.1111 litres of water is present
