Q 13 pls answer its 20 point

Answer 1

Answer:

let number of rupees 50 notes = 3x

                                    20 notes =5x

                                     10 notes = 25 -(3x +5x)

                                                     = 25 - 8x

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

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

170x=590-250

170x=340

x = 340/170

x=2

rupees 50 notes =2x=2x 2=4

rupees 20 notes= 5x=5 x 2=10

rupees 1 notes= 25-8x=25- (8 x 2)=25-16=9
