In a certain code, if FRESH is coded as 6-36-15-76-40,

Solution

In this code, each letter is replaced with the letter that comes after it. However, this difference keeps increasing by one for every subsequent letter. This is how it works: FRESH is coded as 6-36-15-76-40 F = 6 x 1 = 6; R = 18 x 2 = 36; E = 5 x 3 = 15; S = 19 x 4 = 76; H = 8 x 5 = 40 Similarly, S = 19 x 1 = 19; T = 20 x 2 = 40; A = 1 x 3 = 3; L = 12 x 4 = 48; E = 5 x 5 = 25 Code for STALE is 19-40-3-48-25. Hence, the correct answer is (C).
