Answer» Let x men typisst do the typing in (n-5) days And y woment typist do the typing in n days So, `x(n-5)=y(n)` From option (i) Let `x=2p` And `y=5p` `2p(n-5)=5p(n)` `2n-10=5n` `n=-(10)/(3)` not possible From option (ii), `10p(n-5)=3p(n)` `10n-50=3n` `7n=50` `n=(50)/(7)` it is possible From option (iii) `9p(n-5)=7p(n)` `9n-45=7n` `2n=45` `n=(45)/(2)` possible From option (iv) `10p(n-5)=7p(n)` 10n-50=7n` `n=(50)/(3)` possible So, (ii),(iii) and (iv) are possible. |
