Best answer

Let the number of 50-rupee notes with shubhangi be x. 

∴ Number of 20-rupee notes = 2x 

∴ Total amount with Shubhangi = Number of 50- rupee notes × 50 + Number of 20-rupee notes × 20 

= x × 50 + 2x × 20 

= 50x + 40x 

= 90x 

According to the given condition,

∴ Shubhangi has 30 notes of 50 rupees.
