Question

A calculation is shown as:


In the given steps of the calculation, the first error has occured in .

• A. Step 1
• B. Step 2
• C. Step 3

Answer 1

The correct option is A Step 1

We have to calculate the value of
7.93 + 4.8 - 2.17

Here, the first step is 7.93 + 4.8

Now, we know, 4.8 = 4.80

So, 7.93 + 4.8 can be written also as 7.93 + 4.80

Calculating 7.93 + 4.80 using the standard method, we get:


In next step, we have to calculate the value of 12.73 - 2.17

By using the standard method of subtraction, we get:


Listing each of the correct steps, we observe:


Comparing this to the given steps, we find that the first error has occured in Step 1.
