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 mark

Answer 1

Answer:

346.5

Step-by-step explanation:

C scored 300 marks.

B scored 5% more than C.

Hence B's score = 300 + 5% of 300

= 300+ 5/100*300

= 300+ 5*3

= 300+15

= 315

A scored 5% more than B.

Hence A's score = 315 +10% of 315

= 315 + 10/100*315

= 315 + 315/10

= 315 + 31.5

= 346.5
