Question

Out of three given numbers the first num is twice the second and thrice the third if the average of three num is 154 what is the difference between first and third number

Answer 1

Answer:

let the first no. be x

second no. be y

and the third no.be z

A.T.Q

x=2y

x=3z

so 2y=3z

y=3z/2

also,x+y+z/3=154

3z+3z/2+z=154

z=56

y=3z/2=84

x=3z=168
