Rehan buys a book and a pen and pays Rs 50 for both the book costs Rs 8 more than twice the cost of the pen find the cost of the book?

Answer 1

b+p=50

2p+8=b

b-2p = 8

b+p = 50

(multiply bottom by two)

b - 2p = 8

2b + 2p = 100

(add)

3b = 108

108/3 = 36 = b

Book = 36 Rs

Answer 2

Rps 36

Answer 3

Let's denote the cost of the pen as x. The cost of the book is then 2x + 8. Since Rehan pays Rs 50 for both items, we can set up the equation x + (2x + 8) = 50. Simplifying, we get 3x + 8 = 50. Subtracting 8 from both sides gives 3x = 42. Dividing by 3, we find x = 14, which is the cost of the pen. The cost of the book is 2(14) + 8 = 36.
