A box containing 10 pencils costs Rs 22. How much would 7 such boxes of 10 pencils each cost?

Answer

To solve the problem step by step, let's break it down:

### Step 1: Understand the cost of one box
We know that one box containing 10 pencils costs Rs. 22.

### Step 2: Calculate the cost of 7 boxes
To find the cost of 7 boxes, we can multiply the cost of one box by the number of boxes.

\[ \text{Cost of 7 boxes} = \text{Cost of 1 box} \times 7 \]

Substituting the values:

\[ \text{Cost of 7 boxes} = 22 \times 7 \]

### Step 3: Perform the multiplication
Now, we will calculate \(22 \times 7\):

\[ 22 \times 7 = 154 \]

### Step 4: State the final answer
The total cost for 7 boxes of 10 pencils each is Rs. 154.

### Summary of the solution:
- Cost of 1 box = Rs. 22
- Cost of 7 boxes = Rs. 22 × 7 = Rs. 154
