Step1: Calculate total number of pens

Number of pens = $120 \times 25\% = 120 \times 0.25 = 30$

Step2: Calculate blue ink pen count

Blue ink pens = $30 \times 70\% = 30 \times 0.7 = 21$

Step3: Find percentage of total items

Percentage = $\frac{21}{120} \times 100\% = 17.5\%$

Step4: Round to closest option

$17.5\%$ is closest to 18%.
