If 30 men were hired to complete a job in a fixed time. After 40 percent of time elapsed, they could finish only one-third of the work. Due to some reason, the job has to be completed in two-third of the original time. At least, how many more men should be hired to finish the job within this time?

My answer is 45
Can you provide your solution so that I can cross check

yeah, i also got 60.

I got 60 as the answer?

Your method is right but answer is wrong 600/8 is 75 not 50
So additional men required will be 75-30 which is 45

m sorry now i am describing the way ie. fix the time to be 30 minutes,
let the work to be done is 30*30 =900
so, 30*.4 =12 minutes 1/3 of the work ie 300 units are completed
remaining 600 unit are to be now finished in 8 minutes (2/3 of original time -12 minutes)
therefore 600/8=50 as one unit is done by a person in one minute so 50-30 men = 20

20
