B is 22% less than A A is 10% more than D B is 12% less than D A = C |
B is 22% less than A |
25% = \(\frac{1}{4}\) , 20% = \(\frac{1}{5}\) & 10% = \(\frac{1}{10}\) A : B = 5 : 4 , B : C = 4 : 5 & C : D = 11 : 10 Now , A : B : C : D 55 : 44 : 55 : 50 110 : 88 : 110 : 100 By observing these values we find that B is 22% less than A .
