Question

The ratio of 3 candidates A:B:C = 2:3:4 If their total score is 3420. Find the score of each​

Answer 1

Answer:

760, 1140 and 1520

Step-by-step explanation:

A:B:C=2:3:4

Let 2:3:4 be written as 2x, 3x and 4x

Total score is = 3420

EQUATION:- 2x + 3x + 4x = 3420

:- 9x = 3420

:- x = 3420/9

:- x = 380

Now putting x into each candidates' ratio

:- 2×380 = 760

3×380 = 1140

4×380 = 1520

760, 1140 and 1520

Answer 2

Answer:

760, 1140 and 1540 respectively

Step-by-step explanation:

We take A as 2z, B as 2z, C as 4z.

     A           = 2z

     B           = 3z

     C           = 4z

Total score = 3420

  3420        = 2z + 3z + 4z

  3420        = 9z

3420 ÷ 9     = z

   380         = z

     A           = 2 × 380

                   = 760

     B           = 3 × 380

                   = 1140

     C           = 4 × 380

                   = 1540
