Question

The king’s army has $42$ battalions with $750$ soldiers each. The total number of soldiers in the army will be

• A. 3,150
• B. 4,500
• C. 45,000
• D. 31,500

Answer 1

The correct option is D 31,500

Number of soldiers in each battalion = $750$.
Total number of battalions = $42$.

So, total number of soldiers wiil be:
= No. of Battalions $\times$ No. of soldiers in each Battalion
= $42$ $\times$ $750$.

We will use the standard algorithm of multiplication to find the result.

Step 1:
We multiply $750$ by $2$ to get $1500$.


Step 2:
We multiply $750$ by $40$ to get $30000$.



Step 3:
Adding $1500$ to $30,000$, we get the final answer as $31,500$.

From the box diagram also, we can observe that:

Hence, the King's army has a total of $31,500$ soldiers.
