Answer» •Yaman runs a factory. •He makes 2 groups of WORKERS. •He observes that the first group with (a -1) workers has worked for (b+1) day. •The second group with (b+2) workers has worked for (a-1) DAYS. •The productivity RATIO of group 1 to group 2 comes out to be 9/10. •Productivity ratio of group 1 is (a-1)*(b+1) •Productivity ratio of group 2 is (b+2)*(a-1) •Therefore [(a-1)*(b+1)]/[(b+2)*(a-1)] = (b+1)/(b+2) = 9/10 Implies 10B + 10 = 9b + 18 Implies b = 8 |
