Math Problem Statement
P is 40% less efficient than Q and Q, R together can complete a piece of work in 12 days. If P and Q together started the work and after 6 days
R also joined them, then in next 4 days the whole work gets completed. In how many days P alone can complete the whole work?

Formulas
Efficiency of P = 0.6 * Efficiency of Q
Work done by P and Q in t days = t * (Efficiency of P + Efficiency of Q)
Total work done by Q and R in t days = t * (Efficiency of Q + Efficiency of R)
