Option 2 : 45%

Subjects	Number of teachers
Mathematics	25% of 1600 = 400
Physics	18% of 1600 = 288
Chemistry	18% of 1600 = 288
Economics	16% of 1600 = 256
Accountancy	8% of 1600 = 128
Biology	15% of 1600 = 240

Number of male chemistry teachers = 288 -

⇒ 288 - 108

⇒ 180

Required percentage = (180/400) × 100

⇒ 45%

∴ The number of male Chemistry teachers is 45% of the total number of teachers who teach Mathematics.
