$one \: day \: work \: of \: sujata = \frac{1}{30} \\ one \: day \: work \: of \: suchitra = \frac{1}{25} \\ both \: one \: day \: work = \frac{1}{30} + \frac{1}{25} = \frac{5 + 6}{150} = \frac{11}{150} \\ 12 \: days \: work = 12 \times \frac{11}{150} = \frac{22}{25} \\ remaining \: wrk = 1 - \frac{22}{25} = \frac{3}{25} \\ no \: of \: working \: days \: to \: finish \: remainig \: work = \frac{ \frac{3}{25} }{ \frac{1}{30} } = \frac{3 \times 30}{25} \\ = \frac{18}{5} = 3.6days = 4days$
