			   Answer:   Option  D  
			  
		    
Explanation:  
			 
		    
		 
			  (C.P. of 17 balls) - (S.P. of 17 balls) = (C.P. of 5 balls)
=> C.P. of 12 balls = S.P. of 17 balls = Rs.720.
=> C.P. of 1 ball = Rs. 
( 
720 
) 
= Rs. 60.

			   Answer:   Option  C  
			  
		    
Explanation:

			   Answer:   Option  A  
			  
		    
Explanation:  
			 
		    
		 
			  C.P. of 56 kg rice = Rs. (26 x 20 + 30 x 36) = Rs. (520 + 1080) = Rs. 1600.
S.P. of 56 kg rice = Rs. (56 x 30) = Rs. 1680.
∴ Gain = 
( 
80 
x 100 
)% = 5%. 
 
1600
