Question

jagdish has three more 5 ruppe note than 10 rupee notes .if he has RS 195 worth money in total,how many of each kind  notes does he have

Answer 1

answer :
     Let the number of ten rupee notes = x
  therefore , number of five rupee notes = x+3
   Total money = 10*(number of ten rupee notes ) + 5 (number of five rupee notes)
                     = 10*x + 5*(x+3)
                     =10x +5x +15
                     =15x + 15
therefore ,
           15x+15 = 195
           15x = 195 - 15
            15x = 180
             or x = 180/15
                     x=12
Therefore number of ten rupee notes = 12
hence , number of five rupee notes = x+3
                                                         =12 + 3
                                                         =15

Hope this helps you!!

Thank You!!

Answer 2

Answer:

Let the number of 10 rupee notes = x

therefore the numbers of 5 rupee notes = (x+3)

A/Q

10* x +5(x+3)=195

10x +5x + 15 =195

15x+15=195

15x=195-15

15x=180

x=180/15

x=12

Step-by-step explanation:

therefore number of 10 rupee notes = x=12 rupee

number of 5 rupee notes = (x+3)

=(12+3)

=15 rupee
