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

Mean Price

Re.	6
	7

Re. 1

Ratio of water and milk =	1	:	6	= 1 : 6.
	7		7

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

According to question,
Millk = 100 ,
Water = 50/3,
Ratio = 50/3 : 100 = 1 : 6.

@Yuvraj : (16*3+2)/3 = (48+2)/3 = 50/3.

Thats how a mixed fraction is solved.

If 100 is cost price and sp then why do we add 50/3 with cp? Please explain.

Simply,

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

I can't understand how 3/350 is coming? Can anybody help me? please.

1/6=16 * 2/3%.

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

Simple method.

% always denote to 100.

So, 50/3 : 100 = 1/6.
