The ratio of time taken by P, Q and R to complete work
alone is 6:8:4 respectively. If all three together complete the work in 8 days, then find in how many days P alone will complete three-fourth of the same work?
A18 daysCorrect AnswerIncorrect Answer
B9.3 daysCorrect AnswerIncorrect Answer
C22.8 daysCorrect AnswerIncorrect Answer
D19.5 daysCorrect AnswerIncorrect Answer
E12 daysCorrect AnswerIncorrect Answer
Solution
Ratio of efficiency of P, Q & R = 4 : 3 : 6 So, let total work = (4x + 3x + 6x) × 8 = 104x unit Required days = 104x × 3/4 × 1/4x = 19.5 days
