Question

The value of the last digit of a 3-digit number is two times the first digit and three times the middle digit. Find the 3-digit number.​

Answer 1

Answer:

326

Step-by-step explanation:

let's consider the number as xyz

last digit z=2x=3y (given)

take the ratio of X:y:z

=X:2x/3 :2x. (as 2x=3y ; y=2x/3)

= 1: 2/3 :2

the LCM is 3 so the ratio becomes 3:2:6

so the number is 326
