Answer 1

Answer:

hi

your answer is here !

Step-by-step explanation:

Let

No. of currency notes of Rs 50 = 3x

No. of currency notes of Rs 20 = 5x

No. of currency notes of Rs 10 = 25 - (3x+5x) = 25 - 8x

Amount made by Rs 50 notes = 50 × 3x = 150x

Amount made by Rs 20 notes = 20 × 5x = 100x

Amount made by Rs 10 notes = 10 × (25 - 8x) = 250 - 80x

Total money = 590

⇒ 150x + 100x + 250 - 80x = 590

⇒ 170x = 340

⇒ x = 2

Denominations:

Rs 50 = 3 × 2 = 6

Rs 20 = 5 × 2 = 10

Rs 10 = (25 - 8 × 2) = 9
