Question

Max scored $6$ marks more than what he did in the previous examination in which he scored $30$. Maria scored $30$ marks more than she did in the previous examination in which she scored $60$. Who showed less improvement?

• A. Max
• B. Maria
• C. Both showed same improvement
• D. Data insufficient

Answer 1

The correct option is A Max

Max percentage improvement in the first exam $=\frac{6}{30}\times 100\%$

$=\frac{600}{30}\%$

$=20\%$

Maria percentage improvement in the first exam $=\frac{30}{60}\times 100\%$

$=\frac{3000}{60}\%$

$=50\%$

Hence, $20\%<50\%$

Therefore, Max showed less improvement.
