Question

Two numbers are less than a third number by 30% & 37% respectively. How much percent is the second number less than the first
​

Answer 1

Answer:

Let the third number(C) be '100'.

⇒ The first number(A) = (100 - 30)% of 100

⇒ A = 70

⇒ The second number(B) = (100 - 37)% of 100

⇒ B = 63

Now,

Percent by which B is less than by A is

⇒ {(70 - 63)/70} × 100

⇒ 10%

∴ The percentage by which second number is less than the first is 10%.
