Answer 1

let no of 1rs coin be X 

let no of 2rs coin be Y i.e=2X 

after removing all 5rs coin total is 105rs 

hence we have X+Y=105 

thus 3X=105 

thus X=35.. 

there fore no of 1rs & 2rs coins are 35..each 

after taking all 1rs coins... only 35__2rs coins are left.. 

hence total amount left is 2*35= 70 rs
