Shortcut Formulas for Profit and Loss Questions with Examples tml> The ratio of milk to water in a mixture is A:B . if P liters of water is added to the mixture, then milk to water mixture ratio becomes A:C , then the quantity of milk in the mixture is =AP/(C-B) liters And the quantity of water in the mixture is = BP/(C-B) liters If a number x is added to a ratio a:b so that the ratio becomes c:d , Then x= (ad-bc)/(c-d) If there are two numbers whose sum and difference is a and b respectively, then the ratio of those numbers will be = (a+b)/(a-b) if two quantities A and B are in the ratio a:b , then (A+B):(A-B)::(a+b):(a-b) If two numbers are given in the ratio a:b and P in both numbers, the ratio becomes c:d , Then 1^st number = aP(c-d)/(ad-bc) 2^nd number = bP(c-d)/(ad-bc) Sum of numbers = [P(a+b)(c-d)]/(ad-bc) Difference of numbers = [P(a-b)(c-d)]/(ad-bc) If the ratio of incomes of two persons is a:b , and also ratio of their expenses is c:d , and each person saves a sum of x rupees, Then Income of 1^st person = ax(d-c)/(ad-bc) Income of 2^nd person = bx(d-c)/(ad-bc) Example: In a mixture of milk and water, ratio of milk to water is 5:1 . if 5 liters of water is added to the mixture, the ratio becomes 5:2. Determine the quantity of milk in mixture initially? Solution: So in the given question, A=5, B=1, C=2, P=5 Now putting the formula as given above Quantity of milk = AP/(C-B) = (5*5)/(2-1) = 25 liters So the answer is 25 liters of milk is there in the initial mixture of milk and water.
