Question

Saurabh score twice as many runs as Dhoni together their runs fell 7 short of a century how many runs did Dhoni

Answer 1

Let Dhoni scored x runs
So Saurav scored 2x runs (as in question it is given saurav scored twice as many runs as Dhoni)

Both their scores fell short of 100 by 7

So    x+ 2x =100-3
  or    x(2+1)=93
  or   x(3)=93
  or  x=93/3
  or  x= 31

Now  Dhoni scored x runs . So he scored 31 runs
Saurav scored 2x runs. So Saurav scored 2 * 31 runs = 62 runs

Answer 2

let Dhoni score is equal to X
so Saurabh score will be 2 x

X + 2x=93
3x=93
x=93/3
Therefore, x=31
