Question
(x + 9) laborers complete 45% of a task in 12 days working
5 hours/day. The rest is done by (x + 4) laborers in 18 days working 5 hours/day. Find x.Solution
According to the question,
{(x + 9) × 12 × 5}/0.45 = {(x + 4) × 18 × 5}/0.55
Or, 22x + 198 = 27x + 108
Or, x = 18
Hence, value of x is 18.
