does she have?​

Answer 1

Step-by-step explanation:

this is the method

let no. of 5 rupees coins be x

and no. of 2 rupees coins is 3x

and no. of 10 rupees coins is 3x-9

a/q

(2× 3x) + (5x) = 10(3x-9)

6x + 5x = 30x - 90

11x = 30x - 90

90 = 30x - 11x

x = 90/19

2 rupees coins is 270/19

10 rupees coins is 270/19 - 9
