Answer 1

Answer : 10 Boys and 10 Girls will finish the job in 14. 4 Hours or 864 minutes

6 Boys and 10 Girls will finish the job in 24 Hours

10 Boys and 10 Girls will finish the job in ?? Hours

10 Girls can complete the job in 24 Hours . So, in both cases as girls are same the number of boys will decide the time

6 Boys finish the job in 24 Hours

10 Boys will finish the job in LESS time

By using School formula the equation is (LESS/MORE) x No. of Hours

(6/10) x (10/10) x 24 Hours = (0.6) x 24 = 14. 4 Hours

Hence, 10 Boys and 10 Girls will finish the job in 14. 4 Hours or 864 minutes
