Answer 1

Answer:

2rs coins=100 and 5rs coins=160

Step-by-step explanation:

let number of 2rs coins= x

and number of 5rs coins=y

given, 2x+5y=1000----(1)

and x=5y/8

so 5y=8x

putting value of 5y in (1),

2x+8x=1000

10x=1000

x=100 ---- number of 2rs coins

y=8x/5=160 --- number of 5rs coins
