A natural number x is chosen at random from the first 100 natural numbers.Then the probability,for the equation x+100/x>50 is:(A)1/20(B)11/20(C)1/3(D) none of these
Total number of ways of selecting x is 100.Now the given condition is x + 100/x > 50, on analyzing this equation, carefully, we see that this equation is satisfied for all the numbers x such that x > 48 and also for x = 1 and 2So, favourable number cases is 55Therefore, probability = 55/100 = 11/20
