Answer 1

Answer:

Step-by-step explanation:

Let,

Coins of denominations Rs. 1= 5x

Coins of denominations Rs. 2= 9x

Coins of denominations Rs. 5= 4x

So,

Amount of Rs. 1= Rs. 5x*1

= Rs. 5x

Amount of Rs. 2= Rs. 9x*2

=Rs. 18x

Amount of Rs. 5= Rs. 4x*5

= Rs. 20x

A/q,

Amount of Rs. 1+Amount of Rs. 2+Amount of Rs. 5=129

5x+18x+20x=129

43x=129

x=129/43

x=3

Now,

Coins of denominations Rs. 1= 5x= 5*3=15

Coins of denominations Rs. 2= 9x=9*3=27

Coins of denominations Rs. 5= 4x=4*3=12
