A student has 2 books and 1 notebook. The cost of one notebook is Rs. 96. If she sells notebook with first book, she receives the amount twice the value of second book. And if she sells notebook with second book, she receives amount which is less than value of first book by INR 306. What is the value of first book? Correct Answer Rs. 900

Given:

A person has 2 books and 1 notebook. The cost of one notebook is Rs. 96.

Calculation:

Let value of first book be a and value of second book be b

According to statement,

96 + a = 2b

⇒ b = 48 + a/2   ---- (1)

And, 96 + b = a - 306

96 + 48 + a/2 = a - 306

⇒ a/2 = 450

⇒ a = Rs. 900

∴ Value of first book = Rs. 900
