Answer:
12 IND.
Step-by-step explanation:
let T.w = 100 units
R = 100/12 units/day
J = 2/3 *6 * 100 = 100/9 units/day
P = 2/5*10 *100 = 100/25 units/day
alternatively in 3 days
= 100(1/12 + 1/9 +1/ 25) = 211/9
average/day => 211/27 units
work will complete in = 100/211/27
= 12 days
option(A) is correct
