The sum of 5% of 10 and 2% of 2 is:

The correct answer is Option (2) → 0.54

‘Per cent’ means out of a hundred, so \(x\%\) of a number is \(\displaystyle\frac{x}{100}\) times the number. Find each percentage separately and then add the two results, keeping the decimal points in line with each other.

• 5% of 10 is \(\displaystyle\frac{5}{100}\times10=0.5\)

• 2% of 2 is \(\displaystyle\frac{2}{100}\times2=0.04\)

• Adding the two parts: \(0.5+0.04=0.54\)
