- ✓$15\%$
- C$25\%$
- D$23\%$

Answer
Correct option: B.
$15\%$
Marks scored in first test $= 180$
Marks scored in second test $= 150$
Maximum marks $= 200$
Decrease in marks $= 180 - 150 = 30$
Decrease in performance in percentage $=\frac{30}{200}\times100=15\%$
Hence, the correct option is $(b).$
Marks scored in second test $= 150$
Maximum marks $= 200$
Decrease in marks $= 180 - 150 = 30$
Decrease in performance in percentage $=\frac{30}{200}\times100=15\%$
Hence, the correct option is $(b).$
