Question

In a competitive exam of physics, mathematics, and chemistry, Jason scored 60% of his total marks in mathematics. If his total score in the exam is 270, how much did he scored in physics and chemistry in total?

• A. 108
• B. 125
• C. 156
• D. 162

Answer 1

The correct option is A 108

Total marks obtained by Jason = 270
Jason scored 60% of the total marks in mathematics.
Therefore,
Marks obtained by Jason in mathematics = 270 of 60%
= $270\times \frac{60}{100}$
= $27\times 6$
= 162

Therefore, he obtained 162 in mathematics.

Total marks he obtained in physics and chemistry combined
= Total marks – Marks he obtained in mathematics
= 270 – 162
= 108
