First off we know that a number increased by 20 will give us 30. THe only number that can be increased by 20 to give 30, is 10. So now we know that 1/8 of a number will give us 10. To find the number all we need to do is divide 1/8 by 10. 1/8 / 10= 8/1 x 10/1 = 80

now we can test our

1/8 of 80 is 10 and 10 increased by 20 is 30.

Therefore your answer is 80.
