Question

Which digit appears in the tenths place of the decimal number represented by the following grid?

• A. 1
• B. 4
• C. 5
• D. 15

Answer 1

The correct option is B 4

The number represented the first full grid = 1​

In the second grid, we see that 4 squares are completely filled out of 10.​
So, the number represented by it
= $\frac{4}{10}$ = 0.4​

In the 5th square of the second grid 5 portions are colored out of 10.​
So, the number represented by it
= $\frac{5}{10}$ $\times$ $\frac{1}{10}$ = $\frac{5}{100}$ = 0.05​

The decimalnumber represented by the grid = 1 + 0.4 + 0.05 = 1.45​

In the tenths place, we see the digit '4', so it is our answer.​
