Question

The marks of three students A, B and C are in the ratio 4.5.6. If B got 75 marks, then find the
marks of students A and C.​

Answer 1

Step-by-step explanation:

A : B : C = 4 : 5 : 6

If B = 75 marks

Let the ratio be in x

5x = 75

x = 75/5

x = 15

So, A = (15 × 4)

= 60 marks

C = (15 × 6)

= 90 marks

A = 60 marks, B = 75 marks, C = 90 marks

Check -------->

= 60 : 75 : 90

= 4 : 5 : 6
