Answer 1

Answer:

Hence , Sushma need 10 more days to finish the work.

Step-by-step explanation:

Hi,

Given that Sushma can do the embroidery on a saree in 15 days,

In 1 day, Sushma can do 1/15 th of work.

Given that Raveena can do the embroidery on a saree in 10 days,

In 1 day, Raveena can do 1/10 th of work.

Given that Sushma and Raveena worked together for 2 days,

so in 2 days the work completed will be

2*(1/15 + 1/10) = 1/3.

Hence 1/3 rd of work is completed and 2/3 rd of work is rmaining.

Sushma takes 15 days for entire work,

To finish 2/3 rd of work, Sushma will need 2/3 * 15 = 10 days.

Hence , Sushma need 10 more days to finish the work.

Hope, it helps !
