SEETHA GAVE 12 FIFTY RS NOTES TO GET 10 RS NOTES.HOW MANY 10 RS WILL SHE GET FOR IT


(step explanation please )​

Answer 1

Answer:

Step-by-step explanation:

Let the number of Rs. 50 notes and Rs. 20 notes be 5x and 3x respectively.

As she ahs 25 notes in total.

The number of Rs. 10 notes = 25 - (3x + 5x) = 25 - 8x

The amount she has  

Total money = 590

3x × 50 + 5x × 20  + 10 (25 - 8x) = 590

150x + 100x + 250 - 80x = 590

170x = 340

x = 2

The number of Rs. 50 notes = 3 × 2 = 6

The number of Rs. 20 notes = 5 × 2 = 10

The number of Rs. 10 notes = 25 - 8 × 2 = 9
