(2 men + 1 woman) can complete a work in 14 daysSo,(2 men +1 woman)'s 1 day's work $=\;\frac{1}{44}$ Hence, 2 men + 1 woman $=\;\frac{1}{14}$.......(i) Similarly, 2 men + 4 woman $=\;\frac{1}{8}$ .... (ii) On subtracting Eq. (i) from Eq (ii), we get $2\;\text{ men }\;+4\;\text{ woman }\;=\;\frac{1}{8}$ $2\;\text{ men }\;+1\;\text{ woman }\;=\;\frac{1}{14}$$-$   $-$     $-$ ––––––––––––––––––––––––     $\;\;3\text{women} = \frac{1}{8} - \frac{1}{14}$ $\Rightarrow 3\text{ women } = \;\frac{7-4}{56} = \;\frac{3}{56}$ $\Rightarrow 3\text{women} = \frac{3}{56}$ $\Rightarrow 1\text{woman} = \frac{1}{56}$ So, 1 woman can complete the whole work in 56 days From Eq. (i). $\Rightarrow 2\;\text{ men }\;=\;\frac{1}{14} - \;\frac{1}{56}$ $=\;\frac{4-1}{56}$ $\Rightarrow 2\text{men} = \frac{3}{56}$ $\Rightarrow 1\text{man} = \frac{3}{2\times 56}$ So, 1 man can complete the whole work in $\frac{2\times 56}{3}$ days On comparing 1 man and 1 woman work, 56 woman $=\;\frac{56\times 2}{3}$ men ⇒ 1 woman $=\;\frac{2}{3}$ men Hence, amount received by 1 man per day $=\text{Rs }600$ Thus, amount received by 1 woman per day $=600\times\;\frac{2}{3}$ = Rs 400
