Question
The ratio of time taken by P, Q and R to complete work
alone is 4:5:3 respectively. If all three together complete the work in 6 days, then find in how many days P alone will complete three-fourth of the same work?Solution
Ratio of efficiency of P, Q & R = 15 : 12 : 20 So, let total work = (15x + 12x + 20x) × 6 = 282x unit Required days = 282x × 3/4 × 1/15x = 14.1 days
