25 is a perfect square and x is also a perfect square. when x is added to 25 and 1 is substrate from it will give an answer which is also a perfect square. then what is the square root of x?  Choose the most appropriate option: A) 6 B) 2 C) 3 D) 5 E) 4
here   6*6= 
<gadget id="calculator">6*6</gadget>
<output>36</output>
36, 25+36-1=60   2*2= 
<gadget id="calculator">2*2</gadget>
<output>4</output>
4, 25+4-1=28   3*3= 
<gadget id="calculator">3*3</gadget>
<output>9</output>
9, 25+9-1=33   5*5= 
<gadget id="calculator">5*5</gadget>
<output>25</output>
25, 25+25-1=49   4*4= 
<gadget id="calculator">4*4</gadget>
<output>16</output>
16, 25+16-1=40   So 49 is the perfect square of 7   so the answer is 5
<result>D</result>
