 Answer: (a+b)^2=a^2+b^2+2ab = 117+2*54=225 => a+b=15 (a-b)^2=a^2+b^2-2ab = 117-2*54=9 => a-b=3 then a+b/a-b =15/3=5 Answer is 150 men. Explanation : 1 day work = 2/(7*90) 1 hour work=2/(7*90*8) 1 man work=2/(7*90*8*75) The Remaing work 5/7 has to be completed in 60 days , because the total number of days allowed for the completion of the work is 150 days. so we have , (2 * 10 * x * 60) / (7 * 90 * 8 * 75) = 5/7 where x is the number of men working after the 90th day. We get x = 225 Since we have 75 men already, Answer = 225- 75 It is enough to add only 150 men. NOTE: This is objective type question, Please click question title for correct answer.
