Study the following information carefully and answer the questions given below: 

Seven people P, Q, R, S, T, U and V are of different ages. These people appeared for two exams -Mathematics and Science- each of which was of 50 marks. One needs to score at least 20 marks, in order to pass, in each of these 2 subjects.

Average age of R and S is 2 years less than the average age of P and V. Age of P is 20% more than that of V. Q is three years younger than U and the total score of Q is 7 more than that of T. S has got 41 marks in Mathematics and his score in Science is 5 more than twice his age. Marks scored by V in Mathematics is 5 less than the age of Q but 27 less than the marks scored by P in Science. P got 11 marks less in Mathematics than S but 25% more than his own age which is 3 years more than that of S. T failed in one of the subjects by two marks and his score in Science in 21 less than that of P but only 11 less than that of R. Total marks of R is 24 less than that of the person who is 2 years older than him and he scored 12 more marks in Science than Mathematics. The average score of U in both the subjects is 1 more than his score in Mathematics but 2 more than Q's score in Mathematics. Total marks scored by P is 30% more than total marks scored by V, also marks scored by V in Science is 3 more than that of U.
