Question

The king has 10 ministers working for him and each minister earns a salary of 250 gold coins each day. Calculate the total amount the king spends on the salaries of his ministers in one week.

• A. 17,500 gold coins
• B. 15,000 gold coins
• C. 17,000 gold coins
• D. 18,500 gold coins

Answer 1

The correct option is A 17,500 gold coins

Salary earned by 1 minister in 1 day $=250$ gold coins.
There are 10 ministers in the council.

So, salary earned by all $10$ ministers in 1 day $=250\times 10$ gold coins.

Calculating the product using the standard algorithm method,


Therefore, the salary earned by all $10$ ministers in 1 day is $2500$ gold coins.

You know,
1 week has 7 days.

So, the salary earned by $10$ ministers in one week will be:
$2500\times 7$ gold coins.

Calculating the product using the standard algorithm method, you get:


So, $2500\times 7=17,500$.

Hence, the king spends $17,500$ gold coins in a week on the salaries of his ministers.
