Question

in what ratio should water be mixed wid soda costing rs.12/litre so as to make a profit of 25% by selling the diluted liquid at rs.13.75/litre

Answer 1

Here is your answer friend,

_________________

first find the cost price of the mixture by using,

c.p=100/100+gain%*s.p

=100/100+25*13.75

=11

now,among water and soda,water is the cheaper quantity and the price is not given assume it as 0 rs,then simply

0 12

11

1 11

so required ratio is 1:11
