The following pie chart describes the number distribution of research scholars department wise in a university. The strength of scholars of which two given subjects exceeds the combined strength of the scholars from Physics and Mathematics?

Zoology and Education

Combined strength of Physics and Mathematics = 14% + 22% = 36%

By solving one by one for each option ,

1. Zoology and Chemistry

Combined strength of Zoology and Chemistry = 22% + 12% = 34%

2. Hindi and Education

Combined strength of Hindi and Education = 18% + 12% = 30%

3.  Zoology and Education

Combined strength of Zoology and Education = 22% + 18% = 40%

4. Hindi and Zoology

Combined strength of Hindi and Zoology = 12% + 22% = 34%

So , combined strength of Zoology and Education is more than combined strength of Physics and Mathematics.
