On the shelf, there are three books of poetry, five novels, and eight reference works. Suppose we picked two books at random. What is the probability that we pick one novel and one reference work? Choose the correct option A) 1/2 B) 1/3 C) 1/4 D) 1/5 E) 1/6
We could pick one novel and then one reference work, or, we could choose one reference work and then one novel. P(one novel and one reference work) = 5/16*8/15 + 8/16*5/15 = 1/3 The answer is 1/3. <result>B</result>

The difference between a positive proper fraction and its reciprocal is 9/20. The fraction is Choose one. A) 4/5 B) 7/11 C) 7/13 D) 7/15 E) 8/11
Let the required fraction be x. Then 1 - x = 9 x 20 1 - x2 = 9 x 20 20 - 20x2 = 9x 20x2 + 9x - 20 = 0 20x2 + 25x - 16x - 20 = 0 5x(4x + 5) - 4(4x + 5) = 0 (4x + 5)(5x - 4) = 0 x = 4/5 4/5) <result>A</result>

Two trains, each 100 m long, moving in opposite directions, cross other in 10 sec. If one is moving twice as fast the other, then the speed of the faster train is? Choices: A) 22 B) 98 C) 48 D) 88 E) 12
Let the speed of the slower train be x m/sec. Then, speed of the train = 2x m/sec. Relative speed = ( x + 2x) = 3x m/sec. (100 + 100)/10 = 3x =&gt; x = 20/3. So, speed of the faster train = 40/3 = 40/3 * 18/5= <gadget id="calculator">40/3 * 18/5</gadget> <output>48</output> 48 km/hr. Answer:48 <result>C</res...
