Question

Ravi say to Rahul, "give me a hundred, I shall then become twice as rich as you." Rahul replies,"if you give me ten, I shall be six times as rich as you. " find their respective amounts. ​

Answer 1

Answer:

let think rahul had y

and ravi has x

x+100=2y

y+10=6x

x=2y-100

substitute in 2 equation

y+10=6(2y+100)

y+10=12y+600

12y-y=600-10

11y=550

y=55.5
