Question

The area of a garden is 4,099 sq units.
Each team can clean 12 sq units.

Determine the number of teams required to clean the whole area.

• A. 355
• B. 367
• C. 342
• D. 381

Answer 1

The correct option is C 342

Total area of garden = 4099 sq units
Area cleaned by each team = 12 sq units

To determine the number of teams required to clean the entire garden, we have to calculate the value of 4099 $÷$ 12.

Let us solve this through partial quotient method.

First, we write the values in the long division bracket.


Now, we find an easier multiple of the divisor 12, which is closer to the dividend 4,099.


We subtract the multiple 3600 from the dividend 4099 and write the partial quotients in the right column.


Let's keep repeating the process until the dividend is reduced to zero or the remainder is less than the divisor.


Now, we add all the partial quotients.

∴ Final quotient = 300 + 40 + 1 = 341
Remainder = 7

Now, 7 sq units is left to get cleaned.
To clean this area, we need 1 more team.


Hence, number of teams required to clean the garden area 342.
