Sachin scored twice as many runs as Rahul. Together, their runs fell two short of a double century. How many runs did each one score?

उत्तर
Let Rahul’s score be x.
Therefore, Sachin’s score = 2x
Rahul’s score + Sachin’s score = 200 - 2
2x + x = 198
3x = 198
Dividing both sides by 3,
`(3x)/3 = 198/3`
x = 66
Rahul’s score = 66
Sachin’s score = 2 × 66 = 132
