charu completes work in 15 days..work done in one day is 1/15. in the same way..for nirmal it is 1/10. both of them would have worked for one day will be 1/x so.. 1/15+1/10=1/x
15+10/250=1/x
x=6days

rohitgangaraju2: wrong answer

RohitSaketi: yes it is...i did not see the question properly..my bad!
