A shopkeeper sells a badminton racket, whose marked price is ₹ 30, at a discount of 15\% and gives a shuttle cock costing ₹ 1.50 free with each racket. Even then he makes a profit of 20\%. His cost price per racket is
(a)₹ 19.75
(b)₹ 20
(c)₹ 21
(d)₹ 21.25
Answer
Answer (as printed): B
Explanation
Marked price = ₹ 30. $$\text { S.P. }=₹\left[\left(\frac{85}{100} \times 30\right)-1.50\right]=₹(25.50-1.50)=₹ 24 \text {. }$$ Let C.P. be ₹ $x$. Then, $120 \%$ of $x=24 \Rightarrow x=\left(\frac{24 \times 100}{120}\right)=₹ 20$.
