Question

Ragini arranges 12 seeds to form rectangular grids. How many different grids can she make?
  1. 2
  2. 3
  3. 4
  4. 5


Solution

The correct option is B 3

We need to find the number of grids that Ragini can make using 12 seeds.

For this, we need to find the number of ways in which 12 can be expressed as a product of its factors.

12=1×12  
12=2×6
12=3×4 

Thus, three different rectangular grids can be made using 12 seeds as illustrated below.
