Sonia's performance is better

sona scored marks = 437

Sona' percentage = 79.45%

Chetan scored marks = 553

Answer 2

Answer :

Sona performance is better.

Step-by-step explanation ::

To Find:-

• Whose performance is better

Solution:-

Given that,

• Sona scored 437 marks out of 550
• Chetan scored 553 marks out of 700

The percentage of marks Sona scored,

$\sf{\mapsto \: \dfrac{437}{550} \times 100} \\ \\ \\ \sf{\mapsto \: \dfrac{437 \times 100}{550}} \\ \\ \\ \sf{\mapsto \: \dfrac{43700}{550}} \\ \\ \\ \sf{\mapsto \: \cancel{\dfrac{43700}{550}}} \\ \\ \\ \bf{\mapsto \: 79.45\%} \: \: \: \: \: \bigstar$

Therefore, the percentage of marks Sona scored is 79.45%.

The percentage of marks Chetan scored,

$\sf{\mapsto \: \dfrac{553}{700} \times 100} \\ \\ \\ \sf{\mapsto \: \dfrac{553 \times 100}{700}} \\ \\ \\ \sf{\mapsto \: \dfrac{55300}{700}} \\ \\ \\ \sf{\mapsto \: \cancel{\dfrac{55300}{700}}} \\ \\ \\ \bf{\mapsto \: 79\%} \: \: \: \: \: \bigstar$

Therefore, the percentage of marks Chetan scored is 79%.

ACCORDING THE QUESTION,

Sona scored more percentage than Chetan, As

= Sona's percentage > Chetan's percentage

= 79.45 > 79

Hence, Sona scored scored more percentage.
