Question

Which of the following garbage sculptures is/are at least 7.5 feet tall?

• A. Sculpture A
• B. Sculpture B
• C. Sculpture C
• D. Both Sculpture A and Sculpture B

Answer 1

The correct option is C Sculpture C

Let us compare the height of each sculpture with the minimum height 7.5 feet.

Sculpture A has a height of 7.321 feet.

Comparing this height with the minimum height, we get:


The digits at the tenths place are 3 and 5.

$\text{We know,}3<5$

∴ The height of Sculpture A is less than 7.5 feet.

Next, Sculpture B has height 7.499 feet.

Comparing this height with the minimum height, we get:


At the tenths place, we have 4 < 5.

∴ The height of Sculpture B is less than 7.5 feet.

Now, Sculpture C has height of $7.601$ feet.

Comparing this height with the minimum height, we get:


$\text{We have}6>5\text{in the tenths place.}$

So, Sculpture C is taller than 7.5 feet.

∴ Sculpture C is at least 7.5 feet tall.
