A, B and C started a business with their capitals in the ratio 2:3:5. A increased his capital by 50% after 4 months, B increased his capital by 33 1/3 % after 6 months and C withdrew 50% of his capital after 8 months, from the start of the business. If the total profit at the end of a year was Rs. 86,800, then the difference between the shares of A and C in the profit was : A,B और C ने एक व्यवसाय की शुरुआत की जिनकी पूँजी का अनुपात क्रमशः 2 : 3 : 5 है | व्यवसाय के आरंभ से 4 महीने बाद A ने अपनी पूँजी 50% से बढ़ा ली, B ने 6 महीने बाद अपनी पूँजी 33 1/3 % से बढ़ा ली तथा C ने 8 महीने बाद अपनी 50% पूँजी निकाल ली | यदि वर्ष के अंत में कुल 86,800 रुपये का लाभ हुआ, तो इस लाभ में A और C के हिस्सों में अंतर ज्ञात करें |

Two sections of class IX having 27 students in each section appeared for Mathematics olympiad. The marks obtained by them are shown below. 46, 31, 74, 68, 42, 54, 14, 61, 48, 37, 26, 8, 64, 57, 93, 72, 53, 59, 38, 16, 88, 56, 46, 66, 45, 61, 54, 27, 27, 44, 63, 58, 43, 81, 64, 36, 49, 50, 76, 38, 47, 77, 62, 53, 40, 71, 60, 45, 42, 34, 46, 40, 59, 42 One student is selected at random. Find the probability that selected student is having marks more than 49.

Numbers arrangement machine when given an input line of numbers rearranges them following a particular rule in each step The following is an illustration of input and rearrangement {:("Input: 92 54 73 15 40 25 86 77 62 68"),("Step I: 16 92 54 73 40 86 77 62 68 26"),("Step II: 41 16 92 73 86 77 62 68 26 55"),("Step III: 63 41 16 92 73 86 77 26 55 69"),("Step IV: 74 63 41 16 92 86 26 55 69 78"),("Step V: 87 74 63 41 16 26 55 69 78 93"):} Step V., is the last step Input - 59 41 100 29 64 85 17 35 72 88 Which of the following number is 6^(th) to the left of 30 in the III step ?

For teaching the concept of probability, Mrs. Verma decided to use two dice. Shet took a pair of die and write all the possible outcomes on the blackboard. All possible outcomes wave: (1,1), (1,2), (1,3), (1,4), (1,5), (1,6) (2,1), (2,2), (2,3), (2,4), (2,5), (2,6) (3,1), (3,2), (3,3), (3,4), (3,5), (3,6) (4,1), (4,2), (4,3), (4,4), (4,5), (4,6) (5,1), (5,2), (5,3), (5,4), (5,5), (5,6) (6,1), (6,2), (6,3), (6,4), (6,5), (6,6) The probability that 6 will come up on both dice is
