Question
The ratio of time taken by P, Q and R to complete work
alone is 4:6:3 respectively. If all three together complete the work in 6 days, then find in how many days P alone will complete two-third of the same work?Solution
Ratio of efficiency of P, Q & R = 3 : 2 : 4 So, let total work = (3x + 2x + 4x) × 6 = 54x unit Required days = 54x × 2/3 × 1/3x = 12 days
