Answer:
Option C
Explanation:
C.P of 20 dozen = Rs. $(48\times20)$ = Rs. $960$.
C.P of 8 dozen = Rs. $(48\times8)$ = Rs. $384$.
C.P of 12 dozen = Rs. $(960-384)$ = Rs. $576$.
Total S.P = Rs. $\left(\frac{110}{100}\times384+\frac{120}{100}\times576\right)$ = Rs. $1113.60$.
$\therefore$ Profit % $=\left(\frac{153.60}{960}\times100\right)$% $=16$%
