Answer :
Percent means per 100. So, 95 is 95% of 100.
Or, if you want a verbose explanation:
95% of x = 95
∴ (95/100) * x = 95
∴ x = 95 / (95/100)
∴ x = 95 * 100 / 95
∴ x = 100
Or, if you want a verbose explanation:
95% of x = 95
∴ (95/100) * x = 95
∴ x = 95 / (95/100)
∴ x = 95 * 100 / 95
∴ x = 100
