given 3 workers take 96 days to complete a work
then if the same work done by 12 workers how many days they will take
let the days be 'x'
3 ---------------------- 96
12 --------------------- x
3 × 96 = 12 × x
x = 3 × 96/12
x = 3 × 8
x = 24
therefore no. of days it take to complete the work is 24 days
