A bag contains coins of denomination of 50 paise and five rupees. The total value of these coins is Rs. 300. If the total number of coins in the bag is 150, find the number of coins of each type.

Answer: 100 coins each of 50 paisa
               50 coins each of rupees 5 


Solution:      Let number of 50 paisa coins be x coins
                    Therefore, value of 50 paisa coins = Rupees 0.5x
                    Number of Rupees 5 coins = 150 - x coins
                     Therefore, value of Rupees 5 coins = Rupees 5( 150 - x )
                                                                               = Rupees 750 - 5 x
                     by the problem,
                                             0.5x +( 750 - 5 x) = 300
                                         or, - 4.5 x = - 450
                                        or, x = 4500/45
                                       or, x = 100
 
                    Therefore,  Number of Rupees 5 coins = 150 - x coins

                                                                                 = 150 - 100 coins
                                                                                = 50 coins
