Answer 1

HERE OUT OF THE GIVEN 200 DAYS DATA

We can easily observe that in 200 days a total of 40 trains came

i.e 40 days train was present rest 160 days train was not present

NOW AFTER 10 DAYS

AGGREGATE NUMBER OF TRAIN TILL 10 DAYS IS 2

SO remmaing 38 trains came in last 190 days

so proportion of days on which trains was there after 10 days is 38/190 i.e 0.2 or 20%
