Answer 1

Answer:

Step-by-step explanation:Let teh no. Of 10 and 20 notes be x .

No. Of 20 notes =3x

No. Of 10 notes =4x

Acc. To question -

He has 24 notes .

Hence No. Of 5 notes = 24 - 7x (3x+4x)

Hence

Rupees out of 20 notes = 60x

10 notes = 40x

5 notes = ( 24×5 ) - (7x × 5 )

= 120 - 35x

Hence

Total money = 60x + 40x + (120-35x)

250-120=60x + 40x - 35 x

130 = 65x

x = 2
