The letters from A to Z are numbered from 1 to 26 respectively. If GHI = 1578 and DEF = 912, then what is ABC equal to?
492
468
262
246
It is given that A to Z are numbered in same order as 1 to 26 (the word “respectively”). Now, GHI must logically become 789. But we are given GHI = 1578. Note that 789 x 2 = 1578. Also given that DEF = 912. But 912 = 456 x 2 and 456 = DEF in the given coding scheme. So logic is “doubling of give number code”. So correct answer would be ABC = 123 = 246.
