Answer 1

Answer:

Maximum marks =200

Score obtained in first test = 180

$percentage \: of \: marks \: \: in \: first \: test \\ = \frac{180 \times 100}{200} \\ = 90\%$

Score obtained in second test = 150

$percentage \: \: of \: \: marks \: \: in \: \: second \: \: test \: \: \\ = \frac{150 \times 100}{200} \\ = 75\%$

Now his decreased performance = 90-75%

= 15%
