4. A factory consumes 150 units of electricity in 20 minutes. How many units of electricity will
consumed in 3 days?​

Answer 1

Step-by-step explanation:

3. Here,

          Money required to buy 28 candies=Rs. 10

           Money required to buy 63 candies=?

  Now,

        Money required to buy 1 candy= Rs. 28/10

                                                              =  Rs. 2.8

   Again,

           Money required to buy 63 candies= Rs. 2.8x63

                                                                        =Rs. 176.4

Therefore, the money required to buy 63 candies is Rs. 176.4.

4. Here,

          Units of electricity consumed by factory in 20 minutes= 150 units.

          Units of electricity consumed by factory in 3 days=?

   Now,

           Converting days into minutes.

                           1 day=1440 minutes

                           3 day= 1440x3 minutes

                                     = 4320 minutes.

  Again,

            Units of electricity consumed by factory in 1 minute= 150/20 units

                                                                                                 = 7.5 units.

Again,

   Units of electricity consumed by factory in 4320 minutes= 4320x7.5 units

                                                                                                  = 32400 units.

Therefore, Units of electricity consumed by factory in 3 days is 32400 units.
