Explanation:

-> If Capability Price of 1 L of milk = Rs.1
And S.Price of 1 L of combination = Rs.1
Benefits = 20%
Capability Price of 1 L of combination =[ (100 / 100+25)*1 ]
= Rs. 100/125 = Rs. 4/5
-> From the rule of allegation
i. Capability Price of 1 L of water = 0
ii. Capability Price of 1 L of milk = 1
iii. (p) = 4/5
iv. d – m = 1 – 4/5 = 1/5
v. m – c = 4/5 – 0 = 4/5
Ratio of milk to water = 4/5 : 1/5 = 4:1
% of water in the combination = (1/5 x 100)% = 20%
