Answer 1

suppose the number of one rupee coins is 'x'
so the number of two rupee coins is 'x/3'

according to the question,
x+ {2(x/3)} = 115
or, x + (2x/3) = 115
or, 3x + 2x = 3*115
or, 5x = 345
or, x = 345/5
or, x= 69

so, the number of one rupee coins is 69
and the number of two rupee coins is (69/3)= 23.(ans)

hope it will help you....
