​

Answer 1

If in an examination A gets 10% more marks than B and B gets 15% more marks than C, then A will get 26.5% more than C.

Step-by-step explanation:

Let C get “x” marks in the examination.

It is given that, B gets 15% more marks than C

So, B will get marks = x + (15/100)x = 1.15x  

Also given that, A get 10% more marks than B

So, A will get marks = 1.15x + [(10/100)*1.15x] = 1.265x

Thus,

The percentage that A will get more than C will be,

= [(1.265x - x)/x] * 100

= [0.265x/x] * 100

= 26.5%
