Question

In a test of 200 marks each, Richa scored 75.7% and 88.3% in Physics and Chemistry respectively. What are the total marks obtained by Richa in both subjects? a 338 b 322 c 332 d 328​

Answer 1

Answer:

$\sf \green{ \: Given:-}$

• Total number of marks in sch subject= 200
• Marks obtained by Richa in physics= 75.7%
• Marks obtained by Richa in chemistry= 88.3%

$\sf \green{To Find:-}$

• Marks obtained by Richa in both the subject ( marks obtained in chemistry+marks obtained in physics)

So marks obtained by Richa in physics :-

$\implies \sf \frac{75.7}{100} \times 200 = 151.4 \: marks$

And marks obtained by Richa in chemistry:-

$\implies \sf \frac{88.3}{100} \times 200 = 176.6 \: \: marks$

So, Total marks obtained by Richa in both the subject

= Marks obtained in chemistry + Marks obtained in physics

=176.6 + 151.4

=328.0

=328 marks

So, Option D is correct
