it is given that ,

**last year** , the **number **of **boys **in the honor roll is = 60 boys ,

total number of students last year = 160

percent increase in the number of boys in the **honor roll** is = 20% ,

so , number of boys become = 60 + (0.20*60) = 72 boys ,

percent increase in the number of girls in the honor roll is = 3% ,

so , number of girls become = 100 + (0.03*100) = 103 girls ,

**total number** of students** this year** = 103 + 72 = 175 .

**increase **in **number **of **students **= 175 - 160 = 15

So , percent increase is = (15/160) × 100
