20 percent of what number is 100
Hence, 20 percent of the number 500 is 100.
Correct Answer: 100 & 4
Explanation:
Let the first number be x and the second number be y.
Given
5% of x = (25% of y) + y
=> 5x/100 = 5y/4
=> x = 25y ......(1)
and also given that, x - y = 96
=> x = 96 + y .....(2)
From (1)&(2)
25y = 96 + y
=> 24y = 96
=> y = 4
From (1)
x = 96 + 4 = 100
Hence, the numbers are 100 & 4.
