The sum of three numbers is 20. The second number is 4
times the first number , and the sum of the first and third
is8. Find the numbers.
Answer Posted / dheeraj shandilya
Let the three numbers be x, y, z.
Then A/Q second number is four times the first number .
It means y= 4x
so
x+4x+z =20-------(1)
also x+y =8----------(2)
solving these two equation we will get x=3, y= 4x= 12 and
z= 5.
So the three number will be 3, 12, 5
