Show answer & explanation
Correct answer: B
Explanation
The Correct answer is option 2 i.e. Rs. 175
The total cost price of a book and pen is Rs. 371.
Book price = 112% Pen price
Book price/Pen Price = 112/100 = 28/25
Let the price of a book be 28x and the price of a pen be 25x
According to the question
⇒ 28x + 25x = 371
⇒ 53x =371
⇒ x = 371/53
⇒ x = 7
Hence, the cost of a pen is 25x = 25 × 7 = Rs. 175
