The sale price of an article including the sales tax is Rs. 616. The rate of sales tax is 10%. If the shopkeeper has made a profit of 12%, then the cost price of the article is

(A) Rs. 400

(B) Rs. 500

(C) Rs. 525

(D) Rs. 550

Ans: B

110% of S.P. = 616

S.P. = Rs. $$(616 × 100 / 110)$$ = Rs. 560.

∴ C.P. = Rs. $$({100} / {112} × 560)$$ = Rs. 500.

(C) Rs. 65

(D) Rs. 70

Ans: B

(C.P. of 17 balls) – (S.P. of 17 balls) = (C.P. of 5 balls)

⇒ C.P. of 12 balls = S.P. of 17 balls = Rs. 720.
