Answer 1

Answer:

Heya Rakesh Chuahan friends

According to question, marks obtained by Sushant = 1080.

Also, it is said that Mohit has obtained 20% more than Sushant.

= 1080 + 1080 x 0.2 = 1080 + 216 = 1296.

So, let us assume Rajesh scored a marks.

Acc. to ques, a - a x 0.1 = 1296.

or, 0.9a = 1296

or, a = 1296/0.9 = 1440.

Therefore, marks obtained by:

Mohit = 1296

Sushant = 1080

Rajesh = 1440.

Now, % of marks of Rajesh = (1440/2000) x 100 = 72% (Ans)

Now, % of marks of Rajesh = (1440/2000) x 100 = 72% (Ans)
