Financial table with principal (P), simple interest (SI), and amount (A) values.

We are given a table with columns:
- S.No. (Serial Number)
- P = Principal amount
- SI = Simple Interest
- A = Amount (which is P + SI)

The key relationship is:
> A = P + SI

So, to fill in the missing values, we can rearrange this formula as needed:

- If P and A are known → SI = A - P
- If SI and A are known → P = A - SI
- If P and SI are known → A = P + SI

---

Let’s solve each row:

---

(a)

P = $9000, A = $9800 → Find SI
→ SI = A - P = 9800 - 9000 = $800

✔ Answer for (a): SI = $800

---

(b)

SI = $500, A = $4900 → Find P
→ P = A - SI = 4900 - 500 = $4400

✔ Answer for (b): P = $4400

---

(c)

P = $6000, SI = $250 → Find A
→ A = P + SI = 6000 + 250 = $6250

✔ Answer for (c): A = $6250

---

(d)

P = $1800, A = $2420 → Find SI
→ SI = A - P = 2420 - 1800 = $620

✔ Answer for (d): SI = $620

---

(e)

SI = $340, A = $4670 → Find P
→ P = A - SI = 4670 - 340 = $4330

✔ Answer for (e): P = $4330

## ✔ Final Completed Table:

| S.No. | P | SI | A |
|-------|---------|-------|---------|
| (a) | $9000 | $800 | $9800 |
| (b) | $4400 | $500 | $4900 |
| (c) | $6000 | $250 | $6250 |
| (d) | $1800 | $620 | $2420 |
| (e) | $4330 | $340 | $4670 |

## 📝 Explanation Summary:
This problem tests understanding of the basic simple interest formula:
> Amount = Principal + Simple Interest

By rearranging this equation, we can solve for any missing component. No time or rate is involved here — it's purely arithmetic based on the relationship between P, SI, and A.
