Alligation or Mixture
10.
In what ratio must water be mixed with milk to gain 16% on selling the mixture at cost price?
1 : 6
6 : 1
2 : 3
4 : 3
Answer: Option
Explanation:

Let C.P. of 1 litre milk be Re. 1.

S.P. of 1 litre of mixture = Re.1, Gain = 50 %.
3

C.P. of 1 litre of mixture = 100 x 3 x 1 = 6
350 7

By the rule of alligation, we have:

C.P. of 1 litre of water C.P. of 1 litre of milk
0 Mean Price
Re. 6
7
Re. 1

Ratio of water and milk = 1 : 6 = 1 : 6.

Water always be the same amount, i.e, 100.
So the extra gain= mixed water, i.e, 50/3%.
water : milk = 50/3 : 100 = 50 : 300 = 1 : 6.

Gain%,

So, 100 + 50/3 = 350/3.

Simply,

16.66% water to be mixed in 100% milk.
In surd, 16.666/100 = 1/6.

Gain%=16 2/3 which means 1/6.
Gain% = sp/cp.
So,
sp = 1, cp = 6
Ratio = 1:6.

CP of milk = X.

Water is added
SP of mixture= 1.1667X.
1.1667X=X+0.1667X.

X=milk 0.1667X=Water.
0.1667/1.1667=0.142.
14.2% = Water and 85.7 % milk.
14.2/85.7=1/6.
The water and milk are in the ratio of 1:6.

It will be 6:1 not 1:6.

1/6=16 * 2/3%.

So take cost price is 100%.
and 1 : 1/6 = 6:1.

How the selling price of one-litre mixture is 1 re?

How we get to know either they are asking milk to water ratio or water to milk ratio that's why it can be 6:1 and 1:6?
