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. |
