Answers:
A) 80kg	B) 100kg	C) 175kg	D) 320 kg	E) 400 kg
Out of 400, some quantity gave 36% profit &amp; remaining gave 24% loss   Now, 24% loss means -24% profit   From here, we got the 1st row of numbers i.e 36 &amp; -24   The Resultant is again a loss of 12% , so profit of -12%; this will come up in the 2nd row   Using rules of alligation; -12 &gt; -24; so subtracting:   - 12 - (-24) = -12 + 24=

<output>12</output>
12   36 &gt; -12; again subtracting:     36 - (-12)= 
<gadget id="calculator">  36 - (-12)</gadget>
<output>48</output>
48   This gives the 3rd row i.e 12 &amp; 48   So, the total   (12 + 48)= 
<gadget id="calculator">  (12 + 48)</gadget>
<output>60</output>
60, 48 have given a loss of 24%   So, calculation will be   48/(12+48)∗400=320 Answer = 175kg
<result>C</result>
