if the given two numbers are respectively 7 % and 28 % of a third number, then what percentage is the first of the second?  Choose the correct option
A) 20 %	B) 25 %	C) 18 %	D) 30 %	E) none of these
<gadget id="calculator">7 / 100</gadget>
<output>7/100 = around 0.07</output>

<gadget id="calculator">28 / 100</gadget>
<output>7/25 = around 0.28</output>

<gadget id="calculator">(7/100) / (7/25)</gadget>
<output>1/4 = around 0.25</output>

<gadget id="calculator">(1/4) * 100</gadget>
<output>25</output>

<result>B</result>
if the given two numbers are respectively 7 % and 28 % of a third number, then what percentage is the first of the second?
multiply(divide(divide(7, const_100), divide(28, const_100)), const_100)
"here , l = 7 and m = 28 therefore , first number = l / m x 100 % of second number = 7 / 28 x 100 % of second number = 25 % of second number answer : b"
