Question

The consecutive digits of a three-digit number form a G.P. If we subtract 792 from this number, we get a number
consisting of the same digits written in the reverse order and if we increase the second digit of the required number
by 2, the digits of resulting number form an A.P. The number is:
(A) 139
(B) 193
(C) 931
(D) None of these

Answer 1

Answer:

the answer is 931

because if we subtract 792 from 931 we gets 139

if second digit increases by 2 it becomes 5 and 1,5,9 are in AP.
