                8.  Solve the following word problems:

                    (  a)  The cost of a ceiling fan is  3199. What will be the cost of 150 ceiling fans?

                    (  b)  A milk dairy supplies 1250 litres of milk daily. How much milk does it supply in a

              diviSion of nuMbErS


              division by 10, 100 and 1000

                  Š When a number is divided by 10, the ones digit of the dividend becomes the remainder

                  and the number formed by the rest of the digits becomes the quotient.
                  examples:  (a) 56,738 ÷ 10, Q = 5673, R = 8

                                (  b) 2,70,364 ÷ 10, Q = 27,036, R = 4

                  Š When a number is divided by 100, the number formed by the tens and ones digits of
                  the dividend becomes the remainder and the number formed by the rest of the digits

                  becomes the quotient.

                  examples:  (a) 41,036 ÷ 100, Q = 410, R = 36
                                (  b) 5,21,483 ÷ 100, Q = 5214, R = 83

                  Š When  a  number  is  divided  by  1000,  the  number  formed  by  the  hundreds,  tens  and

                  ones digits of the dividend becomes the remainder and the number formed by the rest
                  of the digits becomes the quotient.

                  examples:  (a) 69,273 ÷ 1000, Q = 69, R = 273

                                (  b) 5,00,436 ÷ 1000, Q = 500, R = 436
