Answer 1

Answer:

15 Rs2 coins

25 Rs 5 coins

Step-by-step explanation:

let no. of 2Rs coin be x

then value of 2Rs coins = 2x

APQ

no. of 5Rs coins = x+10

Value of 5 Rs coins= 5(x+10)

= 5x+50

APQ

2x+ 5x+50 = 155

7x = 105

x= 15

So t

no. of Rs 2 coins= x = 15

no. of 5 Rs coins = x+10 = 25
