If 5% of a = b, then b% of 20 is equal to:
Answer & explanation
Correct answer: option 4
⇒ 5% of a = b
⇒ \(\frac{1}{20}\) × a = b
⇒ \(\frac{a}{20}\) × 20% = b × 20% [ multiply by 20% on both side]
⇒ 20% of \(\frac{a}{20}\) = b% of 20
If 5% of a = b, then b% of 20 is equal to:
Correct answer: option 4
⇒ 5% of a = b
⇒ \(\frac{1}{20}\) × a = b
⇒ \(\frac{a}{20}\) × 20% = b × 20% [ multiply by 20% on both side]
⇒ 20% of \(\frac{a}{20}\) = b% of 20
