A salesman makes a 20 percent commission on the selling price of each set of encyclopedias he sells. If he sells 12 identical sets of encyclopedias and makes $1,800 in commissions, what is the selling price of each set?
A. $ 300
B. $600
C. $ 750
D. $ 900
E. $ 1,080
সঠিক উত্তরঃ
C.
$ 750
Explanation:
1800 টাকা discount পায় 12 টা সেটা থেকে। সুতরাং একটি সেট থেকে পায় = 1800 / 12 = 150 20 percent commission= 150. So, actual selling price= 150 *5 = 750 Answer 750.
