A number P is 20% more than a number Q but 10% less than a number R. What percentage is number Q of number R?
Answer & explanation
Correct answer: option 3
20% = \(\frac{1}{5}\) & 10% = \(\frac{1}{10}\)
Ratio of , P : Q = 6 : 5
P : R = 9 : 10
⇒ P : Q : R = 18 : 15 : 20
Required percentage = \(\frac{15}{20}\) × 100
= 75%
