the number of one-rupee coins while the number of
five- rupee coins is half the number of two-rupee
coins. The total amount in the bag is 235. What is
the number of two-rupee coins in the bag?​

Answer 1

Answer:

229 must be the two rupee coin

Answer 2

Answer:

135

Step-by-step explanation:

let no of 1rupee coins be :x

2rupee coins be:5x

5rupee coins be :5x/2

x+5x+5x/2=235

solve it

6x+2.5x=235

8.5x=235

x=235/8.5

x=27

now no of 2 rupee coins =5x=5*27

=135

hence proved
