Answer: A and C together will do it in days.
Step-by-step explanation:
Since we have given that
Number of days A and B can make paintings = 6 days
Number of days B and C can make paintings = 10 days
Number of days A, B, C can make paintings = 4 days.
First we take the L.C.M. of 6, 10, 4 = 60
So, Number of total units = 60 units
Efficiency of A + B =
Efficiency of B + C =
Efficiency of A+B+C =
So,
and
so, Efficiency of A +C = 5+9= 14
So, Number of days A+C will make paintings would be
Hence, A and C together will do it in days.
