D. 12

Work done by P in 1 day = 1/24

Work done by Q in 1 day = 1/9

Work done by R in 1 day = 1/12

Work done by Q and R in 1 day = 1/9 + 1/12 = 7/36

Work done by Q and R in 3 days = 3×7/36 = 7/12

Remaining work = 1 – 7/12 = 5/12

Number of days in which P can finish the remaining work = (5/12) / (1/24) = 10
