Correct Answer: Q

Solution : Let the total amount of work be a.
⇒ Work done by L and P together = $\frac{50}{100}$a = 0.5 a
⇒ Work done by Q alone = a – 0.5 a = 0.5 a
Also, Work done by P and Q together = $\frac{60}{100}$a = 0.6 a
⇒ Work done by P alone = 0.6 a – 0.5 a = 0.1 a
⇒ Work done by L = a – 0.6 a = 0.4 a
$\therefore$ Q is the most efficient.
Hence, the correct answer is Q.
