Answer 1

Answer:

Hope this may help you

Step-by-step explanation:

Let Srishti has 3x notes of Rs 50 and 2x notes of Rs 10 in numbers.

So, number of notes of Rs 20 = (32 – 3x – 2x) = (32 – 5x)

Amount of Rs 50 notes = 50(3x) = Rs (150x)

Amount of Rs 20 notes = 20(32 – 5x) = Rs (640 – 100x)

Amount of Rs 10 notes = 10(2x) = Rs (20x)

Total money she has = Rs 780

150x + 640 – 100x + 20x = 780

or  70x = 140

or  x = 2

The number of Rs 50 notes Srishti has = 6

The number of Rs 20 notes Srishti has = 22

The number of Rs 10 notes Srishti has = 4
