Answer / praveen
let first digit be 'X'
then 5th digit is '3X'
let 2nd digit be 'Y'
then 3rd digit is 'Y-3'
and 4th digit is 'Y+4'
then the no is '(X)(Y)(Y-3)(Y+4)(3X)'
from the above we can say 3X<=9
so X<=3 and any of the digit in the number is <=9
and also given that 3 pairs sum is 11...
so make trial and error..
if X=1...any of the no is 10 which is wrong trial....
if X=2...then let Y+4=9 ==> Y=5
then no is 25296
first pair 2+9=11
second pair 2+9=11
third pair 5+6=11
now the answer is 25296

Answer / ajay singh thakur and rahul ku
let the five digit number is
it is given that
if pairs have sum 11 then possible pairs are
thus the required number contains only these 8 digits
from this we can say that AE,BC and DB cannot be the pairs
by applying operation eq(3)-eq(2) we get
for eq(4) let us check the first possible combination 9+2
obviously this satisfies eq(4)with D=9 and C=2
now from eq(2)and eq(3)
so our number is A529E
now the possible values of A and E are 2 and 6
so from eq(1) it is clear that A=2 and E=6
thus the required number is 25296 which satisfies the given conditions.
