Question 18

The sum of 6 + 12.55 + 5.022 is 23.572.

To find the sum, we add the numbers together: 6 + 12.55 + 5.022 equals 23.572.

A) 18.55

This option is incorrect because it significantly underestimates the total. The addition of 6 and 12.55 alone exceeds 18.55, and including 5.022 only increases the sum further.

B) 23.572

This option is correct as it accurately represents the total when 6, 12.55, and 5.022 are added together. The calculation shows that the sum of these three numbers indeed equals 23.572.

C) 30.572

This option is incorrect because it suggests a total that is too high. The sum of the three numbers does not reach 30.572, as even the largest individual components do not add up to that figure.

D) 16.575

This option is also incorrect. The total of 16.575 is less than the minimum sum of the first two numbers, which alone exceed this value when added together with the third number.

Conclusion

The correct answer, 23.572, is derived from accurately summing the three numbers together. All other options fail to reflect the correct total, either being too low or too high, demonstrating a misunderstanding of basic addition.
