Question

Ramesh buys 10 containers of juice from an online shop and 18 containers of the same juice from another shop.If the capacity of each container is the same and the cost of each of the containers is Rs150,find the total money spent by Ramesh.

Answer 1

Rs. 4200

Explanation:

If Ramesh buys 10 containers, each for 150, we can add 150 + 150 + 150 + 150 + 150 + 150 + 150 + 150 + 150 + 150 (there's ten 150's).

Or, instead of doing a lot of adding, we can use multiplication (repetitive addition is the same thing as multiplication; but instead of adding over and over again, we multiply by how many "groups" of the number that we have. For example, let's say that our group size is 150. If we buy 10 containers, we have bought 10 x 150 containers.)

So, we can use 10 x 150 for the first ten containers. However, we can solve this problem in a slightly more practical way. We can first add the total amount of containers (the total amount of "groups" of 150), 10 + 18 = 28.

So, to solve this equation, we are finding 28 x 150.

150 x 28 = 4200

(150 = size of "group"/price of container)

(28 = amount of "groups"/containers)

So, the total amount of money spent by Ramesh is Rs. 4200
