Two girls begin together to write out a book containing 900 lines. The first girl starts with the first line, writing at a speed of 150 lines per hour and the second girl starts writing from the last line at the rate of 200 lines per hour. At which line will they meet?
Choices: A) 384th line B) 386th line C) 389th line D) 400th line E) None of these
Explanation :   Solve this question as analogous to distance method,   At some x page they will meet, so   x/150 = (900 – x)/200, we get x = 385.7 = 386th line (approx.)   Answer –386th line
