Percentage Practice Test 1 with solutions

Question : 37 of 40

Marks: +1, -0

The difference between two numbers is 30% of the higher number. If the smaller number is 14, find the higher number.

Solution:

Let the higher number be x.
Then, x - 14 = 30% of x

x-14=30/100x

x-14=3/10x

10x-3x=140

7x = 140

x = 20
