If x men can do a piece of work in 8 days and (x+4) men can do the same work in 6 days, then x is equal to
Answer: C. 12
x men's 1 day's work = 1/8 (x + 4) men's 1 day's work = 1/6 Subtracting (i) and (ii), 4 men's 1 day's work = (1/6) - (1/8) = (4 - 3)/24 = 1/24 Now for 1/24 work, men required = 4 for 1/8 work men required = (4 x 24) / 8 = 12 men Hence, x = 12 men.
