Answer:

le

Step-by-step explanation:

let 1rs be x and 2rs be 3x

x+3x=105

4x=105

x=105/4=26.25

so 1rs coin should be 26.25

and 2rs coins should be =3*26.25=78.75

(78.75+26.25=105)

Is it right ?

Answer 2

Number of 1 rupees coin=x

Number of 2 rupees coin= 3x

Value of totalcoin=105RS

X+ two(3x)=105

x+6x=105

7x=105

x=105/7

x=15

Number of 1 rupees coins=x=15

Number of 2 rupees coin=3x=15*3=45
