Question 119

The total marks obtained by Jaya in the maths and Physics together are 50 more than the marks obtained by her in chemistry, if she got 20 marks in the physics .What are her marks in maths?

Solution

Let marks obtained by Jaya in Physics, maths and chemistry respectively be $$p,m,c$$

Marks in physics, $$p=20$$

According to ques, => $$m+p=c+50$$

=> $$m+20=c+50$$

=> $$m-c=50-20=30$$

There is only 1 equation and 2 variables, thus we cannot determine the marks scored by her in maths or chemistry.

=> Ans - (D)
