Question

A got 20% more marks than B and C got 25%
less marks than B. If C scored 300 marks, what
are A's and B's marks?​

Answer 1

Answer:

A mark =400

B mark=375

Step-by-step explanation:

let the a marks be x and b marks by y

now c got 300 marks as given and got 25% less than b

so after finding the 25 less of 300 it will be 225

as 300*25/100=75

300+75=y

375

Now A got 20% more so

225*20/100=25

375+25=x

400=x
