Answer 1

Answer: 70 rs

Step-by-step explanation:

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
