Question

Rahul can do a piece of work in 12 days and Manoj can do the same work in 16/2 days. They work together for 6/2 days and then Manoj leaves. In how many days will Rohit alone finish the remaining work? with explaination and give solution​

Answer 1

Answer:

4.5 days

Step-by-step explanation:

rahul can do 1/12 work in one day

manoj can do 1/8 work in one day

$3( \frac{1}{12} + \frac{1}{8} ) = 3( \frac{20}{96} ) = \frac{5}{8} \\ \\ \frac{3}{8 } \: \: work \: remaining \\ \\ \frac{ \frac{3}{8} }{ \frac{1}{12} } = \frac{3}{8} \times 12 = \frac{36}{8} = 4.5 \: days \: or \: 4 \: days \: 12 \: hours$

6/2=3. 16/2=8
