Question

Rita has 100 rupee notes and 50 rupee notes. Total sum of money she has is 7000. The ratio of 100
rupee notes to 50 rupee notes is 5:4. How many notes of each type does she have?​

Answer 1

Let the note of 100 and 500 rupee be 5x and 4x

Then according to Question

100×5x+50×4x=7000

⇒500x+200x=7000

⇒x=7000/700

⇒x=10

Hence, note of 100 rupee note =5×10=50 notes

Note of 50 rupee =4×10=10 notes.
