Question

in a bag there is hundred 100 coins of 5 rupees in 10 rupees the total sum of coins is 600 rupees then what will be the probability of getting 5 rupee coin out of the bag?​

Answer 1

Answer:

Let number of Rs5 coins be x

Number of Rs 2 coins =3× Number of 5 Rs coins =3x

Number of Re1 coins =160−(x+3x)

=160−4x

Amount of Rs5 coins =5×x=5x

Amount of Rs2 coins =2×3x=Rs6x

Amount of Re1 coins =(160−4×x)

=160−4x

As per the question, Total amount =Rs300

160−4x+5x+6x=300

7x=300−160

x=

7

140

x=20

Number of Re 1 coins =160−4x

=160−4×20

=80

Number of Rs2 coins =3x=3×20=60

Number of Rs5 coins =x=20
