Two numbers are 35% and 50% lesser than a third number. By how much percent is the second number to be enhanced to make it equal to the first number?

20%

25%

30%

40%

Given, two numbers are 35% and 50% lesser than a third number

Let the third number be ‘a’

1st number = a - 35% of a = 0.65a

2nd number = a - 50% of a = 0.5a

Let the % by which second number be enhanced be ‘c’%.

0.5a + c% of 0.5a = 0.65a

⇒ 0.5c/100 = 0.15

⇒ c = 30 %
