Question

If \[5\] buses carry \[200\] passengers. How many passengers can \[20\] bus carry \[?\]

Answer 1

Hint: Using the unitary method we find the solution of the given question. The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value. First find how many passengers one bus carries. To find this, we need to divide the given number of passengers by the number of buses. To find how many passengers \[20\] bus carry, we have to multiply the required number of buses(\[20\]) with the number of passengers one bus can carry.

Complete step-by-step answer:
Given \[5\] buses carry \[200\] passengers.
 we have to divide the given number of passengers i.e., \[200\] by the given number of buses i.e.,\[5\] to get the number of passengers one bus carries.
Then one bus carries \[\dfrac{{200}}{5} = 40\] passengers.
we have to multiply the required number of buses i.e., \[20\] with the number of passengers one bus can carry to get the number of passengers can \[20\] bus carry.
Hence the number of passengers can \[20\] bus carry is \[20 \times 40 = 800\].
So, the correct answer is “800”.

Note: Note that the unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value. This method is used to find the value of a unit from the value of a multiple, and hence the value of a multiple.
