— — — — — — — — — —

Solution:

To calculate his average, we need to get the sum of marks on his tests, then multiply it by number of tests.

`\displaystyle \small \tt Average = (Sum \ of \ marks \ on\ tests)/(Number \ of \ tests) \\\ \\ \tt Avg = (75 + 72+63)/(3) \\\\ \tt \: Avg = (210)/(3) \\\\ \: \tt{Avg = \underline{ \boxed{ \blue{ \bold{70}}}}}`

Hence, his average is 70.

Answer 2

`\huge\boxed{\sf Avg = 70}`

Explanation:

`\displaystyle Average = (Sum \ of \ marks \ on\ tests)/(Number \ of \ tests) \\\\Avg = (75 + 72+63)/(3) \\\\Avg = (210)/(3) \\\\\boxed{Avg = 70}\\\\\rule[225]{225}{2}`

Hope this helped!
