Answer 1

Answer:

$\sf\large\underline\green{answer:} \\ \sf\large\underline\blue{sanju \: 1 \: day \: work = \frac{1}{4}} \\ \\ \\\large\underline\red{sumit \: 1 \: day \: work = \frac{1}{6}} \\ \\ \sf\large\underline\green{(sanju + sumit) \: 1 \: day \: work = \frac{1}{6} + \frac{1}{4} = \frac{2 + 3}{12} = \frac{5}{12}} \\ \\ \sf\large\underline\red{ans = \frac{12}{5} = 2\frac{2}{5} \: days}$

Answer 2

Sanju can do a piece of work=1/4

Sumit can do it in = 1/6

work together= 1/4+1/6 = 3+2/12 = 5/12

then reciprocal it then you will get = 12/5
