Answer : [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
420
 x 100   % =
1475

Answer : [B]
Explanation :
 
Let C.P. = Rs. x, Profit% = x% and S.P. = Rs. 144.
 
 
 x =  
100
(100 + x)
 x 144  
 
x2 + 100x = 14400
 
x2 + 100x - 14400 = 0.    
 
   x2 + 180x - 80x - 14400 = 0     (x + 180) (x - 80) = 0     x = 80.

Answer : [A]
Explanation :
 
(C.P. of 36 mangoes) - (S.P. of 36 mangoes) - Loss = (S.P. of 4 mangoes)
 
    S.P. of 40 mangoes = C.P. of 36 mangoes.      
 
Let C.P. of each mango be Re. 1.
 
C.P. of 40 mangoes = Rs. 40; S.P. of 40 mangoes = Rs. 36.
 
 
  Loss% =
