Question

If we need 3 packs of batteries and there are 8 batteries in each pack, how many batteries we need?

  1. 16
  2. 36
  3. 30
  4. 24

Hint:

The total number of Batteries will be equal to the product of the total number of pack required and the total number of Batteries in each pack. We are given the both the values and we just need to multiply them to get the number of batteries.

The correct answer is: 24


    The total number of Batteries will be equal to the product of the total number of pack required and the total number of Batteries in each pack.
    Step1: Calculating the total number of Batteries need.
    In this question we are given that we have 3 pack of batteries and each pack have 8 batteries. So, the total number of batteries will be equal to:
    Batteries = N u m b e r space o f space P a c k s space cross times space B a t t e r i e s space i n space 1 space P a c k
    =>3 cross times 8
    =>24.
    So, the total number of batteries required will be equal to 24
    Alternate Solution
    Step1: Considering Multiplication as addition
    We know that multiplication is just an addition of numbers. This can be understood as follow,
    When we say 5 multiply by 25 cross times 2, we are basically adding 5 two times like this
    5 cross times 2 space equals space 10
5 plus 5 space equals 10
    Step2: Calculating the total number of batteries
    So, to get the total number of batteries we just need to add total number of batteries in each box to the total number of pack times. We need to add 8, 3 times
    8 plus 8 plus 8 space equals 24
    Hence the total number of batteries required will be 24
