$\huge {\underline {\underline {\mathbb {\pink {A{\blue{n{\green{s{\orange {w{\purple {e{\red{r}}}}}}}}}}}}}}}$

Let the number of 10 rupee notes be x

so the number of 50 rupee notes are x-1

Now

10x + 50(x-1) = 250

10x + 50x -50 = 250

60x - 50 = 250

60x = 250 +50

60x = 300

x = 300/60 = 5

Therefore

no of 10 rupee notes = 5

no of 50 rupee notes = 4
