# My uncle changed a 1000 rupee cheque from a bank in the form of 5 rupee and 10 rupee notes. If he received 137 notes in total then find the number of 5 rupee notes that he got.

Let the number of 5 rupee notes got by uncle be x.

As it is given he gets total of 137 notes, so number of 10 rupee notes he get will be

137-x

It is given adding these notes the total amount should be 1000.

Hence the equation becomes,

5(x)+10(137-x)=1000

5x+1370-10x=1000

1370-5x=1000

1370-1000=5x

5x=370 So uncle got 74,5-rupee notes,

And 137-x=137-74=63,10-rupee notes.
