A can complete a work in 16 days.
A can complete 1/16 work in 1 day.
B is 60% more efficient than A.
B can complete 1.6 *1/16 = 1/10 work in 1 day.
so B will complete full work in 10 days.

ratio of time taken by a and b = 160 : 100 => 8:5
now 8:5 :: 16 : x
then x=10 days

10 days..
Explanation: According to the question B=1.6A, and A can complete the work in 16 days. So A's 1 day work is = 1/16. Then B's 1 day work is 1.6/(16) = 1/10, so B can finish the work in 10 days.
