⇒ One - day work of P = 1/25
⇒ One - day work of Q = 1/50
⇒ One - day work of both P and Q together = 1/25 + 1/50 = 3/50
⇒ Total time taken by them = 50/3 days
⇒ Time taken for 18% work = (18/100) × (50/3) = 3 days
⇒ One - day work of Q = 1/50
⇒ One - day work of both P and Q together = 1/25 + 1/50 = 3/50
⇒ Total time taken by them = 50/3 days
⇒ Time taken for 18% work = (18/100) × (50/3) = 3 days
