Study the following information carefully and answer the questions given below: c o Eight boxes namely A1 to A8 are kept one above the other in a shelf having nine racks. One of the racks is empty which is not immediately below box A2. The number of books in each box is different viz.- 14, 21, 23, 39, 28, 17, 52, and 42. The box which e e contains 14 books is kept third from the bottom. Two boxes are kept between the box which contains 14 books and box A2. The box adjacent to A2 is kept three places away from A3, which contains 21 books. The vacant rack is neither above box A2 nor below the box which contains 14 books. Three boxes are kept between the box which contains 21 boxes and the box A7, which is not kept at the bottom. The number of books in box A4 is 3/4th of the number of books in the box kept three places above box A6 which contains 14 books. The number of books kept in box A7 is a prime number. The sum of the number of books in box A7 and box A4 is twice the number of books in box A5. Two boxes are kept between box A8 and box A1, which is kept immediately above the box which contains 39 books. Box A5 is neither kept adjacent to the box which contains 23 books nor box A3. What is the number of books from box A1?

Explanation

Given, the box which contains 14 books is kept third from the bottom. Two boxes are kept between the box which contains 14 books and box A2. The vacant rack is neither above box A2 nor below the box which contains 14 books. That means, the box A2 is kept third from the top. The box adjacent to A2 is kept three places away from A3, which contains 21 books. That means, in case (1) the box A3 is kept at the top, in case (2) A3 is kept at two places below box A2. Based on the above given information we have: e e w w Again, we have: Three boxes are kept between the box which contains 21 boxes and the box A7, which is not kept at the bottom. That means, in case (1a) A7 is kept two places below A2, in case (1b) A7 is kept at three places below A2, in case (2) A7 is kept at the top. The number of books from box A4 is 3/4th of the number of books from the box kept three places above box A6 which contains 14 books. Here only such possible combinations are (28, 21) & (52, 39). But the number of books from A3 is 21, thus the only possible number of books from A4 = 39. The number of books from box A7 is a prime number. Thus, the number of books from box A6 is 14. The sum of the number of books from box A7 and box A4 is twice the number of books from box A5. Since, the number of books from the box is A7, thus, the only possible combination is (17, 39 & 28). Based on the above given information we have: Again, we have: Two boxes are For Free kept visit Demo, between box A8 and or www.ixamBee.com box A1, which Contact is kept immediately us at 9205524028 above the box which contains 39 (SMS/WhatsApp/call)
