Maths question

The manager would NOT accept the workers'counter proposal.

Let $A the original annual salaries of the workers.

Consider the manager's proposal :
Annual salaries of the workers in next year = $A(1 + 10%) = $1.1S
Annual salaries of the workers in the following year = $1.1A(1 + 20%) = $1.32A
Total salaries of the workers in the two years = $(1.1A + 1.32A) = $2.42A

Consider the workers' counter proposal :
Annual salaries of the workers in next year = $A(1 + 20%) = $1.2A
Annual salaries of the workers in the following year = $1.2A(1 + 10%) = $1.32A
Total salaries of the workers in the two years = $(1.2A + 1.32A) = $2.52A

Obviously, the factory will pay more for the workers' counter proposal. Therefore, the manager would not accept it.

To 山下智久 :

請留意 "The manager would not accept it." 與 "The manager does not accept it" 的分別。

(無聊同離題,可無視)
條問題無話manager點樣先會reject worker個proposal
即使工人個proposal要支付的薪金 多過 manager 個proposal要支付的薪金,可能個manager都會accpet 班workers既要求
