how???
Lcm of 8 & 16 that is total units of work. then 1/8 unit work done by A. 1/16 unit work done by B in a day. that means 1/16 + 1/8 units of work done in 2 days. means 3/16. just make numerator close to 16. It is 5x3 / 16 = 15 / 16.means within 10 days they have completed 15 units. left with 1 unit and next is B turn. that is 11th day
thanks
