                        View Hint View Answer Discuss in Forum Let the C.P. of the watch be Rs. 100. 
 ∴ Its S.P. = Rs. 125
 If S.P. > C.P. , then
 Profit = S.P. - C.P. = 125 - 100 = Rs. 25∴ Profit percent on its S.P. = Profit × 100 S.P. 
 Correct Option: BLet the C.P. of the watch be Rs. 100. 
 ∴ Its S.P. = Rs. 125
 If S.P. > C.P. , then
 Profit = S.P. - C.P. = 125 - 100 = Rs. 25∴ Profit percent on its S.P. = Profit × 100 S.P. Profit percent on its S.P. = 25 × 100 = 20% 125

                        View Hint View Answer Discuss in Forum Let the C.P. of each book be Re. 1. 
 ∴ Total C.P. of 25 books = Rs. 25
 Their S.P. = Rs. 20
 If C.P. > S.P. , then
 Loss = C.P. of 25 books - S.P. of 25 books = 25 - 20 = Rs. 5∴ Loss percent =  Loss  × 100 C.P. of 25 books 
 Correct Option: ALet the C.P. of each book be Re. 1. 
 ∴ Total C.P. of 25 books = Rs. 25
 Their S.P. = Rs. 20
 If C.P. > S.P. , then
 Loss = C.P. of 25 books - S.P. of 25 books = 25 - 20 = Rs. 5∴ Loss percent =  Loss  × 100 C.P. of 25 books = 5 × 100 = 20% 25

 Correct Option: AGiven , First S.P. = Rs. 1040 , Gains = 4% and Second S.P. = Rs. 950 C.P. of tape recorder = Rs. 100 × First S.P. ( 100 + Gain% ) C.P. of tape recorder = Rs.  100 × 1040  = Rs. 1000 104 
 On selling for Rs. 950,
 Loss = Rs. (1000 – 950) = Rs. 50∴ Loss percent = 50 × 100 = 5% 1000

- 
                        View Hint View Answer Discuss in Forum Let C.P. of each article be Re. 1. 
 ∴ C.P. of 40 articles = Rs. 40
 S.P. of 40 articles = Rs. 50
 Profit = S.P. of 40 articles - C.P. of 40 articles = 50 - 40 = Rs. 10∴ Profit percent = Profit × 100 % 40 
 Correct Option: ALet C.P. of each article be Re. 1. 
 ∴ C.P. of 40 articles = Rs. 40
 S.P. of 40 articles = Rs. 50
 Profit = S.P. of 40 articles - C.P. of 40 articles = 50 - 40 = Rs. 10∴ Profit percent = Profit × 100 % 40 Profit percent = 10 × 100 = 25% 40
