Read the following information carefully and answer the questions given below:

Six persons A, B, C, D, E and F are of different height but not necessarily in the same order. A is 2nd tallest person among them. There are two persons between A and B. C is just taller than D but shorter than E. The height of the 2nd tallest person is 177cm.

If the sum of height of A and D is 300cm, and the height of B is 114cm then what is the sum of the height of B and D?

The correct option is 237m.

Let us break down the information step-by-step to find the sum of the heights of B and D:

Step 1: Determine the height of A
- We are given that six persons (A, B, C, D, E, and F) have different heights.
- A is the 2nd tallest person among them.
- The height of the 2nd tallest person is 177 cm. Therefore, the height of A is 177 cm.

Step 2: Find the height of D
We are given that the sum of the heights of A and D is 300 cm:

$\text{Height of A}+\text{Height of D}=300$

Substitute the height of A (177 cm) into the equation:

$177+\text{Height of D}=300$

$\text{Height of D}=300-177$

$\text{Height of D}=123\text{cm}$

Step 3: Calculate the sum of the heights of B and D
- The height of B is given as 114 cm.
- Now, we add the heights of B and D:

$\text{Sum}=\text{Height of B}+\text{Height of D}$

$\text{Sum}=114+123$

$\text{Sum}=237\text{cm}$

Thus, the sum of the heights of B and D is 237 cm (which is written as 237m in the options list).
