Question

Haseena bought 1 pencil box, 4 pencils and 4 notebooks from a store. She paid Rs. 95 in all. Some ink fell on the bill that she got from the store. So the price of 1 notebook cannot be seen from the bill. What is the price of the one notebook?​

Answer 1

23.75

Explanation:

Let's assume the price of the pencil box is P, the price of each pencil is Q, and the price of each notebook is R.

According to the given information, Haseena bought 1 pencil box, 4 pencils, and 4 notebooks. Therefore, we can write the following equations:

P + 4Q + 4R = 95 (Equation 1)

However, due to some ink falling on the bill, we cannot see the price of one notebook. To solve this problem, we need to eliminate the variable R from Equation 1.

We can rewrite Equation 1 as:

4R = 95 - P - 4Q (Equation 2)

Now, let's consider some possible values for P and Q to find the value of R.

Case 1: Let's assume P = 0 and Q = 0. In this case, Equation 2 becomes:

4R = 95 - 0 - 0

4R = 95

R = 95/4

R = 23.75
