In the previous post we learnt how to multiply any number from 30 to 39 by 5 in seconds.Today we are going to learn another amazing trick to multiply any number from 40 to 49 by 5 in seconds.

Let us see the steps

**Step 1:** Assume the base as 40

**Step 2:** Multiply the base by 5

**Step 3:**Multiply the unit place digit by 5

**Step 4:**Add the results obtained in step 2 and step 3 to get

final answer.

Now lets consider a few examples to understand better

**Example 1:43 x 5 = ?**

**Step 1:**We assume the base as 40.

**Step 2:**Multiplying the base by 5

We get 40 x 5 = 200

**Step 3:**Multiplying the unit place digit by 5

We get 3 x 5 =15

**Step 4:**Adding results obtained in step 2 and step 3

We get 200 + 15 = 215

**Ans 43 x 5 = 215**

**Example 2:48 x 5 = ?**

**Step 1:**We assume the base as 40.

**Step 2:**Multiplying the base by 5

We get 40 x 5 = 200

**Step 3:**Multiplying the unit place digit by 5

We get 8 x 5 = 40

**Step 4:**Adding results obtained in step 2 and step 3

We get 200 + 40 = 240

**Ans 48 x 5 = 240**
