Question

The sum of rs 82 is made of 209 coins which are either 25 paise coins of 50 paise coins

Answer 1

Hi,

You have to put an equation system.

Let x be the pieces of 25 and y the pieces of 50.

x + y = 209

25x + 50y = 82

50( x + y) = 50x + 50y = 10 450

50x + 50y = 10 450

- 25x + 50y = 82

----------------------------------

25x + 0y = 10 368

x = 10 368 / 25 = 414,72
