Answer:
      let number of one rupee coins = x
therefore , number of 50 paisa coins = 3x
Total amount of money = Rs 35
therefore ,
   0.5(3x) + 1(x) = 35
.15x +1x= 35
or 25/10x=35
or 25x= 35*10
or 25x =350
or x= 14
Therefore , Number of one Rupee coins = 12
Hence Number of 50 paisa coins = 3*14 = 42

HOpe this Helps You :)
Cheers!!!!!!!!!!

hey sorry I have taken the total as 30 instead of 35
but still your answer is wrong !!!
bla bla bla my ans is 100% correct ok?
my ans is correct
25x = 350 or x= 14 hence number of 1 rupee coins = 14 and therefore number of 50 paisa coins = 3x =3*14 = 42 ..

Let no. of one rupee coins be x = 1 * x = x
               fifty paise coins = 3x = 3 * 50x/100 = 15x/10
  
A.T.Q

x  +  \frac{15x}{10} = 35 
 \frac{10x}{10}  \frac{15x}{10} = 35               (LCM=10)
 \frac{25x}{10} = 35
25x = 35 * 10
x =  \frac{350}{25}
x = 14

no. of 1 rupee coin = x = 14
no. of 50 paise coin = 3x = 14 * 3 = 42
1 5 1
hey number of 50 paisa coins = 3*14 = 42
your last step is incorrect!!
