Question

a text boook of mathmaics costs 2 rupees more than a text book of literature if 5 literature books cost 38 rupees more than 3 mathematics books what is the costs of each lioterature 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.
