Solution
Let the number of 1Rs coins be 5x
And the number of 2Rs coins be x
total value of coins =70
so,1×5x +2×x=70
. 5x+2x=70
. 7x=70
. x=10
therefore no. Of 1rs coins=5x=5×10=50
. And no. Of 2rs coins=x=10
And the number of 2Rs coins be x
total value of coins =70
so,1×5x +2×x=70
. 5x+2x=70
. 7x=70
. x=10
therefore no. Of 1rs coins=5x=5×10=50
. And no. Of 2rs coins=x=10
