Answer:

120%

Step-by-step explanation:

Let the numbers be x and y

2nd number =20 + x

20 + x/x × 100

Let 2nd number be 100

1st number is 100 + 20 = 120

120/100 × 100 = 120%

Answer: Given that,

The second number is 25% more than 100.

The first number is 20% less than the second number.

Now,

The second number is

= 100 + 25% of 100

= 100 + 25

= 125

Similarly,

The second number is

= 125 - 20% of 125

= 125 - 25

= 100

Hence, the first number is 100.
