Answer 1

90of 50p and 45 of 1 Rupees

Answer 2

Answer:

Step-by-step explanation:

suppose number of 1 rupee coins =2x

And number of 50paise coins=x

Then, according to question

1*2x + 0.5*x=90

2x+0.5x=90

2.5x=90

X=90/2.5

X=36

So the number of 1 rupee coin is 2x=2*36=72

And the number of 50paise coin is x=36.

That's all

Thanks you
