- if the second number is x
- then the first number will be 2x
- and the third number will be 3x
According to the question,
x+2x+3x=270
6x=270
x=270/6=45
therefore the second number is 45
the first number is 45*2=90
the third number=45*3=135
to check our ans,
LHS RHS
45+90+135 = 270
LHS=RHS therefore our ans is correct..
