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 8 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) Ă— 8 = 72x unit Required days = 72x Ă— 2/3 Ă— 1/3x = 16 days
