Answer 1

Answer:

100

Step-by-step explanation:

Given Manoj can do a work in 20 days, while chandu can do the same work in 25 days. They started the work jointly. A few days later suresh also joined them and thus all of them completed the whole work in 10 days. All of them were paid total rs.1000. What is the share of suresh?

Efficiency of Manoj will be 5%

Efficiency of Chandu will be 4%

So in days working together they will be able to complete (5 + 4) x 10 = 90% of work.

So remaining work that is 10% will be done by Suresh.  

Therefore Suresh will get 10% of Rs 1000 = Rs 100

Answer 2

Answer:

100

Step-by-step explanation:

Efficiency of Manoj = 5%

Efficiency of Chandu = 4%

They will complete only 90% of the work = [(5+4)*10] =90

Remaining work was done by Suresh = 10%.

Share of Suresh = 10/100 * 1000 = 100
