Solution

The correct option is B 40 + 2 = 42
In the given image, there are 4 rods and 2 unit cubes. We know that 1 rod = 1 Tens or 10, and 1 unit cube = 1 Ones or 1.
So, 4 rods = 4 Tens or 40, and 2 unit cubes = 2 Ones or 2.
Hence, the number and its expanded form represented in the image is: 40 + 2 = 42
