Answer: A) 15 Explanation: Let number of hit shots be 'X'Let number of miss shots be 'Y'Given X + Y = 40....(1)50X - 10Y = 500.....(2)Solving 1 and 2, we getX = 15 and Y = 25Therefore, number of hits = 15

Answer: D) 120 Explanation: In given word OLIVER there are 3 vowels E, I & O. These can be arranged in only one way as dictionary order E, I & O.   There are 6 letters in thegiven word.   First arrange 3 vowels.   This can be done in 6C3 ways and that too in only one way.(dictionary order E, I & O)   Remaining 3 letters can be placed in 3 places = 3! ways   Total number of possible ways of arranging letters of OLIVER = 3! x C36 ways = 6x5x4 = 120 ways.

Answer: B) Rs. 6540 Explanation: Given C.I = 5984, R = 20% , T = 2yrs  C.I = P1+201002-1   5984 =    => P = (5995x25)/11   P = Rs. 13625   Now S.I = PTR/100   SI = (13625 x 8 x 6)/100 = Rs. 6540

Answer: C) 82.5 Explanation: The given series    12   24   26.5   79.5   ?   330 follows a pattern that,   12 x 2 = 24   24 + 2.5 = 26.5   26.5 x 3 = 79.5   79.5 + 3 = 82.5   82.5 x 4 = 330   Hence, the missing number is 82.5

Answer: C) 2 Explanation: Total money decided to contribute = 750 x 12 = 9000 Let 'b' boys dropped The rest paid 150/- more => (12 - b) x 900 = 9000 => b = 2 Hence, the number of boys who dropped out is 2.

Answer: B) 37.33 sec Explanation: Speed = 108 km/hrenter a tunnel,, means that the train covers a distance equal to its own lengthso (108 x 5/18) = x/4 where x= length of trainhence x = 120 mtrsto pass completely train has to travel a distance = (x + tunnel length) that is 1120 mtrs.so (1120/t) = (108x5/18)t = 37.33 sec

Answer: D) 84.8 Explanation: Let 'M' be the maximum marks in the examination. Therefore, Madhu got 32% of M = 32M/100 = 0.32MAnd Kumar got 42% of M = 42M/100 = 0.42M.In terms of the maximum marks Kumar got 0.42M - 0.32M = 0.1M more than Madhu. ---- (1) The problem however, states that Kumar got 16 marks more than the cut-off mark and Madhu got 8 marks less than the cut-off mark. Therefore, Kumar has got 16 + 8 = 24 marks more than Madhu. ---- (2) Now, Equating (1) and (2), we get0.1M = 24 => M = 24/0.1 = 240'M' is the maximum mark and is equal to 240 marks.We know that Madhu got 32% of the maximum marks.Therefore, Madhu got 32 x 240/100 = 76.8 marks.We also know that Madhu got 8 marks less than the cut-off marks. Therefore, the cut-off marks will be 8 marks more than what Madhu got = 76.8 + 8 = 84.8.

Answer: C) Rs. 1400 Explanation: We know thatThe Difference between Compound Interest and Simple Interest for n years at R rate of interest is given by C.In - S.In = PR100n Here n = 2 years, R = 20%, C.I - S.I = 56 56 = P201002=> P = 56 x 52=> P = 56 x 25=> P = Rs. 1400
