In this question, some equations are solved on the basis of a certain system. On the same basis find out the correct answer from amongst the four alternatives for the unsolved equation.
If a man takes 25 minutes to reach railway station and his train is scheduled at “$%”. Then at what time should he leave to reach the station 10 minutes earlier?
Scheduled time of train = “$% = 5:20 To reach station 10 minutes earlier = 5:20 – 10 minutes = 5:10 Man take 25 minutes to reach station = 5:10 – 25 minutes = 4:45 = “%#”
In the question, a word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in two matrices given below. The columns and rows of Matrix I are numbered from 0 to 4 and that of Matrix II are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g., G can be represented by 04, 40, etc., and 'K' can be represented by 56, 75, etc.
Similarly you have to identify the set for the word 'NILE'.
A man travels 10 km towards west, then he takes a turn towards north-east and travels 20 km in the direction. He again takes a turn towards south-east and covers 5 km. Taking starting point as the origin, in which direction is he now?
