Question

The following calculation was performed by the Royal Treasurer.

His first error was in step number

• A. 1
• B. 2
• C. 3

Answer 1

The correct option is B 2

We can split $32$ as $30$ $+$ $2$.

So, to multiply $32$ with $3132$, we have to first multiply $3132$ with $2$.

Now, in Step $1$, we get:
$3132\times 2=6264$


In the second step, we will multiply $3132$ with $30$.
But, in Step 2, the "correct" answer will be:
$3132\times 30=93960$.


But, on comparing, we can see that the Royal Treasurer had wrongly calculated it as $3132\times 3=9396$.
The zero after 9396 is missing.

So, the first error made by the Royal Treasurer is in "Step 2".
