Match List-I with List-II.
| List-I | List-II | ||
|---|---|---|---|
| (A) | \(x\%\) of 25 = 2.125 | (I) | 70 |
| (B) | 9% of \(x\) = 6.3 | (II) | 16 |
| (C) | \(x\%\) of 45 = 22.5 | (III) | 8.5 |
| (D) | 0.25% of \(x\) = 0.04 | (IV) | 50 |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A) - (III), (B) - (I), (C) - (IV), (D) - (II)
\(x\%\) of a number means \(\frac{x}{100}\) of it, so each equation is solved for \(x\).
(A) \(x\%\) of 25 = 2.125 — this matches (III) 8.5.
\(\displaystyle x=\frac{2.125\times100}{25}=8.5\)
(B) 9% of \(x\) = 6.3 — this matches (I) 70.
\(\displaystyle x=\frac{6.3\times100}{9}=70\)
(C) \(x\%\) of 45 = 22.5 — this matches (IV) 50. 22.5 is half of 45.
\(\displaystyle x=\frac{22.5\times100}{45}=50\)
(D) 0.25% of \(x\) = 0.04 — this matches (II) 16.
\(\displaystyle x=\frac{0.04\times100}{0.25}=16\)
