A train leaves P at 9 am with speed of 30 km/h. Another train leaves Q at 11 am with speed of 45 km/h. The trains are travelling towards each other on parallel tracks. Distance between P and Q is 300 km. When they meet, what is the ratio of the distances covered by them? एक ट्रेन सुबह 9 बजे 30 km/h की गति से P से निकलती है। एक अन्य ट्रेन सुबह 11 बजे 45 km/h की गति से Q से निकलती है। ट्रेनें समानांतर पटरियों पर एक-दूसरे की ओर जा रही हैं। P और Q के बीच की दूरी 300 km है। वे कब मिलेंगीं, एवं उनके द्वारा तय की गई दूरियों का अनुपात कितना होगा?

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 shown in the given two matrices. The columns and rows of Matrix-l 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, for example, 'C' can be represented by 11, 67, etc., and 'E' can be represented by 22, 58, etc. Similarly, you have to identify the set for the word "FOLK".
