Question

A text book of mathematics cost rupees 2 more than a textbook of literature. If 5 literature book cost rupees 38 more than 3 mathematics book. What is the cost of literature book?

Answer 1

Let each literature text book cost be Rs. X
Then, cost of mathematics text book = Rs. (X + 2)
ATQ,
5X = 38 + 3(X + 2)
5X = 38 + 3X + 6
2X = 44
X = 22.
 
Therefore, cost of each literature text book = Rs. X = Rs. 22.
And that of masthematics = X + 2 = Rs. 24.

Answer 2

Let each literature text book cost be Rs. X

Then,cost of mathematics text book= Rs.(X + 2)

ATQ,
5X = 38 + 3(X + 2)
5X = 38 + 3X + 6
2X = 44
X = 22.

Therefore, cost of each literature text book = Rs. X = RS. 22.
And that of Mathematics = X + 2 = Rs. 24.
