Let total work to be done = 70 units => Efficiency of A = $$frac{70}{14} = 5$$ units/day and Efficiency of B = $$frac{70}{5} = 14$$ units/day Thus, efficiency of A & B together = $$5 + 14 = 19$$ units/day $$ herefore$$ Time taken by A and B together do the same work = $$frac{70}{19} = 3 frac{13}{19}$$ days
