Answer: 32 workers can complete the work in 10 days
Explanation: 1/8 work by 8 workers in 5 days. If the same 8 workers work another 5 days then another 1/8 gets done. Hence, total 2/8 = 1/4 work is completed by 8 workers in 5+5= 10 days. If 8 workers complete 1/4 work in 10 days, the number of workers required to complete all the work = 8 x 4 = 32
