1. The proportion of acid and water in three samples is 2 : 1, 3 : 2 and 5 : 3. A mixture containing equal quantities of all three samples is made. The ratio of water and acid in the mixture is -

A. 120 : 133

B. 227 : 133

C. 227 : 120

D. 133 : 227

Solution:

According to the question,

\begin{matrix} Acid Water Total \\ \begin{matrix} Sample I 2_{\times 40} = 80 : 1_{\times 40} = 40 3_{\times 40} \\ Sample II 3_{\times 24} = 72 : 2_{\times 24} = 48 5_{\times 24} \\ Sample III \underline{5_{\times 15} = 75} : \underline{3_{\times 15} = 45} 8_{\times 15} \end{matrix}] 120 \end{matrix}

Ratio of quantity 227 : 133

Required ratio  = 133 : 227
