Let’s go through each question one by one and solve them carefully.

---

Question 1: Which of the following can also be written as 84%?

We know that “percent” means “per hundred”, so:

84% = 84/100

Now simplify 84/100:

Divide numerator and denominator by 4 → 21/25

So, 84% = 21/25 → That’s option [B]

Check others quickly:
- [A] 0.16 = 16% → No
- [C] 8.4 = 840% → No
- [D] 84/25 = 3.36 = 336% → No

✔ Correct answer: [B] 21/25

Question 2: All of the following are equal except:

Let’s calculate each:

[A] 50% of 400 = 0.5 × 400 = 200

[B] $200 → obviously 200

[C] $400 decreased by half = 400 - (half of 400) = 400 - 200 = 200

[D] 150% of 50 = 1.5 × 50 = 75 ← This is different!

[E] $100 increased by 100% = 100 + 100 = 200

So only [D] is not equal to 200.

✔ Correct answer: [D] 150% of 50

**Question 3: Express the sample proportion as a percent.
379 out of 659 applicants for jobs had the necessary skills.**

Proportion = 379 ÷ 659

Let’s compute that:

379 ÷ 659 ≈ ?

Do division: 379 ÷ 659

≈ 0.5751 (use calculator or long division)

Convert to percent: multiply by 100 → 57.51%

Round appropriately — since it's about people, maybe round to nearest whole percent? But let’s keep one decimal unless told otherwise.

Actually, let’s check more precisely:

379 ÷ 659 = ?

Compute:

659 × 0.575 = 659 × 0.5 = 329.5; 659 × 0.075 = ~49.425 → total ~378.925 → very close to 379

So yes, approximately 57.5%

But perhaps we should give exact value rounded reasonably.

In most school contexts, rounding to nearest tenth of a percent is fine.

So: 379 ÷ 659 ≈ 0.5751 → 57.5%

✔ Final Answer: 57.5%

Question 4: 20% of 60 is what number?

20% = 0.20

0.20 × 60 = 12

✔ Final Answer: 12

---

Question 5: 80% of 50 is what number?

80% = 0.80

0.80 × 50 = 40

✔ Final Answer: 40

---

Question 6: Compare Column A and Column B

Column A: 80% of 72,000
= 0.80 × 72,000 = 57,600

Column B: 20% of 288,000
= 0.20 × 288,000 = 57,600

They are equal!

✔ Correct answer: [C] The quantities are equal.

Question 7: 18 is 60% of what number?

Let the number be x.

Then: 60% of x = 18
→ 0.60x = 18
→ x = 18 ÷ 0.60
→ x = 30

Check: 60% of 30 = 0.6 × 30 = 18 → Correct.

Options: [A] 333 [B] 10.8 [C] 30 [D] 0.3 → So [C]

✔ Correct answer: [C] 30
