Answer:
Option A
Explanation:
Remaining work =1−47 =37
Remaining period =(46−33) days = 13 days.
Let the total men working at it be x.
Less work, Less men (Direct Proportion)
Less days, More men (Indirect Proportion)
More Hrs/Day, Less men (Indirect Proportion)
{Wrok47:37Days13:33Hrs/Day9:8}::117:x
47×13×9×x =37×33×8×117
or x=(3×33×8×1174×13×9) =198
Additional men to be employed =(198−117) = 81.
