Sure.
Out of 400, some quantity gave 36% profit & remaining gave 24% loss
Now, 24% loss means -24% profit
From here, we got the 1st row of numbers i.e 36 & -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 > -24; so substracting:
- 12 - (-24) = -12 + 24 = 12
36 > -12; again substracting:
36 - (-12) = 48
This gives the 3rd row i.e 12 & 48
So, the total (12 + 48) = 60, 48 have given a loss of 24%
So, calculation will be
\(\frac{48}{(12+48)} * 400 = 320\) = Answer = C
Hope this would be helpful
