first we will take out 70 percent of 17 than subtract it from 17 that is
70/100*17=11.9
11.9=ans

17-11.9
answer = 5.1 days

Answer:

B

Step-by-step explanation:

Ratio of times taken by kishore and Dinesh = 170 : 100 = 17 : 10.

Suppose Dinesh takes x days to do the work.

17 : 10 :: 17 : x -- > x = ((17x 10)/17 ) = 10

therefore,x = 10 days.

Hence, Dinesh takes 10 days to complete the report.
