Q:
A text book of mathematics cost 2 Rs/- more than a text book of literature. If 5 literature books cost 38 Rs/- more than 3 mathematics books, what is the cost of each literature book?
Answer & Explanation
Answer: B) 22
Explanation: 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.
