उत्तर : 1. "20"
व्याख्या :
Answer: A) 20 Explanation: Let the runs scored by P, Q, R, S and T be a, b, c, d and e From given data, a + b + c + d + e = 36 x 5 = 180b + c = 107Let a = xe = x-8d = x-3now 3x - 11 + 107 = 1803x = 84x = 28e's score = 28-8 = 20

उत्तर : 2. "&N4 and @E9"
व्याख्या :
Answer: B) &N4 and @E9 Explanation: plan is given in first step. Total count of letters is 4 and last letter is N and ‘p’ is coded as & so Final answer will be- &N4 We have to find 'translate' code. As we can see that this word is not given in any steps but as we know the idea of that so we can solve it. Step I: first we will count the letters of that word that is 9, then we put digit 9 at the right end. Step II: we will put the last letter of that word then it will like- E9 Step III: at the last step ‘t’ is coded for ‘@’(first letter of each word is coded by a specific symbol like here ‘t’ is coded for ‘@’. We can find the first coded symbol by looking at the other given words. Answer will be - @E9

प्र: Two pipes A and B can fill a tank in 24 hours and 1717 hours respectively. Harihar opened the pipes A and B to fill an empty tank and some times later he closed the taps A and B , when the tank was supposed to be full. After that it was found that the tank was emptied in 2.5 hours because an outlet pipe "C" connected to the tank was open from the beginning. If Harihar closed the pipe C instead of closing pipes A and B the remaining tank would have been filled in : 10535 05b5cc7cfe4d2b419777511cc

उत्तर : 2. "8 hours"
व्याख्या :
Answer: B) 8 hours Explanation: Efficiency of Inlet pipe A = 4.16% 10024 Efficiency of Inlet pipe B = 5.83% 1001717 Therefore, Efficiency of A and B together = 100 % Now, if the efficiency of outlet pipe be x% then in 10 hours the capacity of tank which will be filled = 10 * (10 - x) Now, since this amount of water is being emptied by 'C' at x% per hour, then 10x10-xx=2.5 hrs => x = 8 Therefore, in 10 hours 20% tank is filled only. Hence, the remaining 80% of the capacity will be filled by pipes A and B in 80/10 = 8 hours
