if in coded language MARY=9108 SORA=68886 Then JOHN=?
write the letter in reverse order and give the position as 1, 2
z(1),y(2),x(3),w(4),v(5),u(6),t(7),s(8),r(9),q(10),p(11),o(12),n(13),m(14),l(15),k(16),j(17),i(18),h(19),g(20),f(21),e(22),d(23),c(24),b(25),
a(26)
mary = 14*26*9*2=6552 + add reverse of digit 6552 = 6552+2556=9108
sora=8*12*9*26=22464+46422=68886
john=17*12*19*13=50388+88305= 138693
so answer is 138693
