Answer 1

Answer:

let Rekha ,Nidhi and Jaya won medals are 2x,3x,5x

according to question,

3x=12

x=12\3

x=4

hence,

2x=2×4=8

5x=2×5=10

Answer 2

Answer:  Rekha = 8

               Jaya = 20

               Total = 40

Step-by-step explanation: Ratio is 2:3:5

Let the common factor be x .

So medals won by Rekha = 2x

Jaya = 5x

Nidhi = 3x = 12

So , x = 12/3 = 4  and Rekha = 2 x 4 = 8 and Jaya = 5 x 4 = 20

Total no. of medals = 2x + 3x + 5x = 10x = 10 x 4 = 40

Thus , this is the answer .
