A can finish a piece of work in 24 days. B is 20% more efficient than A and C is 25% more efficient than B. Find the time B and C will take to finish the work?

Answer
9days
Explanation :
A= 1/24
B = 120/100(1/24) = 1/20
C= 125/100(1/20) = 1/16
B+C =(1/20) + (1/16) = 16+20/320 = 36/320 = 8.88 = 9 days
