 
 <translate> Work done by X in 1 day = 1/24
Work done by Y in 1 day = 1/16
Work done by Y in 10 days = 10/16 = 5/8
Remaining work = 1 – 5/8 = 3/8
Number of days in which X can finish the remaining work = (3/8) / (1/24) = 9
Thus, the answer is (E). <ibo> Ọrụ X rụrụ n'otu ụbọchị = 1/24 Ọrụ Y rụrụ n'otu ụbọchị = 1/16 Ọrụ Y rụrụ n'ụbọchị iri = 10/16 = 5/8 Ọrụ fọdụrụ = 1 <unk> 5/8 = 3/8 Ọnụ ọgụgụ ụbọchị nke X nwere ike ịrụcha ọrụ fọdụrụ = (3/8) / (1/24) = 9 N'ihi ya, azịza ya bụ (E).
