Question

An empire has 23 kingdoms and each kingdom has 20 ministers. If 20% of all the ministers are male, the total number of male ministers in the empire is

• A. 75
• B. 80
• C. 77
• D. 92

Answer 1

The correct option is D 92

No. of kingdoms in the empire $=23$.
No. of ministers in one kingdom $=20$.

∴ Total number of ministers in the empire $=23\times 20=460$.

$20\%$ of all the ministers are males.
Now, we know,
$20$% $=\frac{20}{100}=\frac{1}{5}$.

So, number of male ministers in the knigdom =
$\frac{1}{5}\times 460$$=\frac{460}{5}=92$.

Therefore, the total number of male ministers in the empire is $92$.
