Question

12. If three numbers are in the ratio of 1:2:3 and half the
sum is 18, then the ratio of squares of the numbers
is:
(a) 6:12:13
(b) 1:2:4
(c) 36:144:324 (d) 3:5:7

so the solution is
let no be x, 2x ,3x
then
x + 2x + 3x / 2 = 18
why we divided it by two because in question it asked half the sum

then
x + 2x + 3x / 2 = 18
6x = 36
x = 6

6, 12 , 18
then final it asked square of the no.
then answer will be option c
that is
36, 144, 324.​
