Question

If 48 workers working for 8 hours a day can finish building a wall in 9 days If each worker works for 6 hours a day, find the number of workers to finish the same wall in 8 days​

Answer 1

Answer:

72 workers

Step-by-step explanation:

In 9 days working 8 hours need 48 workers

In 1 day working 1 hour need 48 × 9 × 8 workers

(since days and hours are inverse variation with workers so we multiplied to find unit day & hour)

In 8 days working 6 hours need (48×9×8)/(8×6)=72

Ans: 72 workers
