Anshu multiplied 160 by 89 instead of multiplying by 79. How much was his answer greater than the correct answer ?

Options

A. 1600
B. 16000
C. 10060
D. 10640

Answer

To find out how much greater Anshu's incorrect answer is compared to the correct answer, we will follow these steps:

### Step 1: Calculate the correct answer
Anshu was supposed to multiply 160 by 79.

\[ \text{Correct Answer} = 160 \times 79 \]

Calculating this:

\[ 160 \times 79 = 12640 \]

### Step 2: Calculate the incorrect answer
Anshu mistakenly multiplied 160 by 89 instead.

\[ \text{Incorrect Answer} = 160 \times 89 \]

Calculating this:

\[ 160 \times 89 = 14240 \]

### Step 3: Find the difference between the incorrect answer and the correct answer
Now, we need to find out how much greater the incorrect answer is than the correct answer by subtracting the correct answer from the incorrect answer.

\[ \text{Difference} = \text{Incorrect Answer} - \text{Correct Answer} \]

Calculating this:

\[ \text{Difference} = 14240 - 12640 = 1600 \]

### Final Answer
The difference between Anshu's incorrect answer and the correct answer is **1600**.
