Shubhangi has twice as many 20- rupee notes as she has 50-rupee notes. Altogether, she has 2700 rupees. How many 50-rupee notes does she have?

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, 

90x = 2700 

∴ x = 2700/90 = 30

∴ Shubhangi has 30 notes of 50 rupees.
