MCQ-> The English alphabet is divided into five groups. Each group starts with the vowel and the consonants immediately following that vowel and the consonants immediately following that vowel are included in that group. Thus, the letters A, B, C, D will be in the first group, the letters E, F, G, H will be in the second group and so on. The value of the first group is fixed as 10, the second group as 20 and so on. The value of the last group is fixed as 50. In a group, the value of each letter will be the value of that group. To calculate the value of a word, you should give the same value of each of the letters as the value of the group to which a particular letter belongs and then add all the letters of the word: If all the letters in the word belong to one group only, then the value of that word will be equal to the product of the number of letters in the word and the value of the group to which the letters belong. However, if the letters of the words belong to different groups, then first write the value of all the letters. The value of the word would be equal to the sum of the value of the first letter and double the sum of the values of the remaining letters.For Example : The value of word ‘CAB’ will be equal to 10 + 10 + 10 = 30, because all the three letters (the first letter and the remaining two) belong to the first group and so the value of each letter is 10. The value of letter BUT = $$10 + 2 \times 40 + 2 \times 50 = 190$$ because the value of first letter B is 10, the value of T = 2 $$\times$$ 40 (T belongs to the fourth group) and the value of U = 2 $$\times$$ 50 (U belongs to the fifth group). Now calculate the value of each word given in questions 161 to 165 :AGE

MCQ-> Study the following information carefully and answer the questions given below: Eight persons — E, F, G, H, W, X, Y and Z — are sitting in two parallel rows containing four persons each. E. F, G and H are sitting in row-1 facing north and W. X, Y and Z are sitting in row-2 facing south (but not necessarily in the same order.) Thus, each person sitting in row – 1 faces another person sitting in row – 2, Each of the two rows consists of one Doctor, one Engineer, one Pilot and one Scientist (but not necessarily in the same order). • The Doctor of row-1 sits second to the right of H. X faces one of the immediate neighbours of H. Only one person sits between the X and the Scientist. • The one who faces the Scientist of row – 2 is an immediate neighbour of E. Only one person sits between E and the Pilot. • W sits second to the right of Z. Y does not face G. The Scientist of row-1 faces the Engineer of row – 2. • G faces one of the immediate neighbours of the Doctor of row-2. The Doctor of row-2 does not sit at any of the extreme ends of the line. Z is not a Doctor.Which of the following represents the people sitting at extreme ends of both the lines?

MCQ-> Study the following information carefully and answer the questions giver. below. Eight persons E, F, G, H, W X, Y and Z are sitting in two parallel rows containing four persons each in such a way that there is an equal distance between adjacent persons. E, F, G and H are sitting in row-1 facing north and W, X, Y and Z are sitting in row-2 facing south. (but not necessarily in the same order.) Thus, each person sitting in row-1 faces another persons sitting in row-2 Each of the two rows consists of the one Professor, one Leader, one Technician and one Doctor (but not necessarily in the same order). • The Doctor of row-1 sits second to the right of H. E is an immediate neighbour of H. E faces the Leader of row-2. • X sits to the immediate right of the Leader. X faces one of the immediate neighbours of the Professor of row-1. The Professor of row-1 does not sit at any of the extreme ends of the line. • W sits second to the left of Y. Z does not face G. F faces the Professor of row-2. In both the rows, onlye one person sits between the Professor and the Technician. W is not a Doctor.Which of the following represent both the immediate neighbours of W ?
