Answer 1

Answer:

Here you have 3 variables and 3 equations,so the answer is straight.

Here you have 23 coins with 3 different denominations (₹1,₹2,₹5).

1.Let 'a' be number of ₹1 denomination coins

'b' be number of ₹2 denomination coins.

'c' be number of ₹5 denomination coins

So total coins is 23=a +b +c

2.Ratio of ₹1 coins to ₹2 coins is 3:2

So a:b=3:2 ,it means a=1.5b

3.The total value of these coins is ₹43

So a+2b+5c=43

Now you 3 equations to solve for 3 variables a,b,c 1. a+b+c=23

2. a=1.5b

3. a+2b+5c=43

Solving this you get a=12, b=8 ,c=3

So you have 12 coins of ₹1, 8coins of ₹2 and 3 coins of ₹5.

The value of ₹1 coins is 12×₹1=₹12

Value of ₹2 coins is 8×₹2. =₹16

Value of ₹5 coins is 3×₹5. =₹15
