There is no such number since,  1468=(31*47)+11Where 31 & 47 are prime numbers and cannot divide (1361-7) or 1361.

Present age of father is 22 years
as father is 22 years so son is 22-18=4 years
after 5 years father is 27 and son becomes 9 year which makes father thrice age of his son

Let Sons present age = x years
so, fathers present age = x+18 years
after 5 years, sons age will be = x+5 years
fathers age will be = x+23 years
according to the problem,
x+23 = 3 (x+5)
or, 2x=8
or, x=4
so, fathers present age is (4+18) years = 22 years
