Two numbers are less than a third number by 30% and 37% respectively. By how much is the second number lesser than the first?
Answer & explanation
Correct answer: option 4
Let 3rd Number = 100x
1st number = 100x - 30% of 100x = 70x
2nd number = 100x - 37% of 100x = 63x
Required percentage = \(\frac{70x - 63x }{70x}\) × 100 = 10%
