Question

In a test, a scored 10% more than b and b scored 5% more then

c. If c scored 300 marks out of 400, then a's marksare

Answer 1

B's marks = C's marks + 5% of 400 = 300 + 20 = 320

Now, A's marks = B's marks + 10% of 400 = 320 + 40 = 360

Answer 2

Answer:

Step-by-step explanation:

C score=300/400

B=5%+c

A=10%+b

5%of 300=5/100 X 300=15

B score = 300+15=315

10%of 315=10/100 X 315=31.5

A score=315+31.5=346.5
