The difference between a two-digit number and the number obtained by interchanging the digits is 36. What is the difference between the sum and the difference of the digits of the number if the ratio between the digits of the number is 1 : 2 ? | [
"4",
"16",
"17",
"8"

III.The length of the train Q is 180 metres. | [
"I only",
"III only",
"Even with I, II and III, the answer cannot be obtained.",

Let the length of the train P be x metres.
II. These trains are running in opposite directions.
III. Length of the train Q is 180 m.
I.Time taken by P to cross Q = (180 + x)/Relative speed
18 = (180 + x)/Relative speed
Thus, even with I, II and III, the answer cannot be obtained.
