			   Answer:   Option  B  
			  
		    
Explanation:  
			 
		    
		 
			  Cost Price (C.P.) = Rs. (4700 + 800) = Rs. 5500.
Selling Price (S.P.) = Rs. 5800.
Gain = (S.P.) - (C.P.) = Rs.(5800 - 5500) = Rs. 300.
Gain % = 
( 
300 
x 100 
)% 
= 5

			   Answer:   Option  B  
			  
		    
Explanation:  
			 
		    
		 
			  Let C.P. of each article be Re. 1 C.P. of x  articles = Rs. x .
S.P. of x  articles = Rs. 20.
Profit = Rs. (20 - x ).
∴  
( 
20 - x  
x 100 = 25 
) 
 
x  
 
 
  2000 - 100x  = 25x 
125x  = 2000
  x  = 16.

			   Answer:   Option  B  
			  
		    
Explanation:  
			 
		    
		 
			  Let C.P. be Rs. x  and S.P. be Rs. y .
Then, 3(y  - x ) = (2y  - x )   → y  = 2x .
Profit = Rs. (y  - x ) = Rs. (2x  - x ) = Rs. x .
∴ Profit % = 
( 
x  
x 100 
)% = 100%

			   Answer:   Option  B  
			  
		    
Explanation:  
			 
		    
		 
			  Let C.P.= Rs. 100. Then, Profit = Rs. 320, S.P. = Rs. 420.
New C.P. = 125% of Rs. 100 = Rs. 125
New S.P. = Rs. 420.
Profit = Rs. (420 - 125) = Rs. 295.
∴ Required percentage = 
( 
295 
x 100 
)% 
= 
1475 
% = 70% (approximately).
