Explanation:

Let’s break this down step by step:

- Given numbers of chocolates: 250, 190, 119, 175, 280, 210.

- Boxes: P, Q, R, S, T, U.

Clues and deductions:

- P is immediately above R.

- Three boxes between R and the box with 250 chocolates.

- The 175 chocolates box is just above the 250 chocolates box.

- One box between T and the box with 175 chocolates.

- U contains 210 chocolates.

- The 119 chocolates box is below U.

- Three boxes between S and the 119 chocolates box.

- One box between Q and the 190 chocolates box.

Placing the boxes:

- Box with 119 chocolates must go somewhere below U.

- U can’t be bottom (because must have a box below it) or top (no box above it for “just above” clues).

- Only possible unique order after stepwise placement is:

1. S

2. U (210)

3. P

4. R

5. T

6. Q

Assignment of numbers by clues:

- Assign each number according to relationships; you’ll get:

1. S – 280

2. U – 210

3. P – 175

4. R – 250

5. T – 119

6. Q – 190

- R and T contain: 250 + 119 = 369 chocolates.

Options:

1. 399

2. 369

3. 294

4. 309

5. 400

The correct answer is Option 2: 369.

Here’s why: R (250) and T (119) add up to 369, matching Option 2, not Option 4. Always good to check your final placements!
