Question
84 is divided into two parts in such a way that the
fourth part of the first part and the fifth part of the second are in the ratio 1 : 2. The first part is approximately what percent of the second part?Solution
First part = x and second part = 84 – x = `(x/4)/((84-x)/5) = 1/2` ⇒`x/4xx5/(84-x)= 1/2` ⇒ 10x = 336 - 4x ⇒ 14x = 336 ⇒x = 24 Second part will be 84 – 24 = 60 Required percentage = `24/60xx100 = 40%`
