Answer 1

Answer:

There are total 60 coins.

Step-by-step explanation:

The coins are in the prop. 1:3.

Let total number of 25 paise coins be X and total number of 10 paise coins be Y.

Putting these amounts in the proportion, we get:

=25×1+10×3

=25+30=55

Now, the total amount is 8.25 rupees that is 825 paise.

Dividing the total amount by why the sum of amount in proportion, we get:

=825/55

=15

So, 15=X

We know, X=Y/3

=3X=Y

=45=Y

OR Y=45

So, total number of coins will be:

X+Y=45+15

=60

Justification:

We have the equation:

25x+10y=825

25×15+10×45=825

375+450=825

825=825

Hence, Justified.
