Answer 1

Answer:

rs. 5 notes = 240

rs. 2 notes = 36

Step-by-step explanation:

Let the no. of 5 rs coin be X and the no. of 2rs notes be y.

A to Q

5x+2y=1272 - (i)

also, y = 15% of x

= 15x /100 - (ii)

By placing value of y in eq (i)

5x + 2(15x/100) = 1272

5x + 15x / 50 = 1272

So, X = 240

and y = 15(240)/100

= 36
