Question

There are 5 rows in a class with 32 students sitting in each row. Each student has a flute.

So, the total number of flutes is .

• A. 150
• B. 155
• C. 160

Answer 1

The correct option is C 160

Number of students in each row = 32

Number of flutes with
each student = 5

∴ Total number of flutes with the students = 32 $\times$ 5

The expanded form of 32 is:
32 = 30 + 2


So, we can write 32 $\times$ 5 as:

Let's draw a table and write 30 and 2 on top of the second and third column and 5 in the first column of the second row.

Now, we fill the table by multiplying the numbers in the corresponding rows and columns.

At last, we add all the products to get the final answer:
150 + 10 = 160


Hence, 160 flutes are required.
