Question

If 3 workers take 96 days to complete a work then how days will 12 workers take?

Answer 1

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

Answer 2

3×96=X×12                                                                                                        ⇒3×96÷12=X                                                                                                       ⇒X=24
