In a certain coding language, HE is coded as 418 and GO is coded as 240. How will SHE be coded in that language?

HE is coded a 418.

If we look at the inidivial letter, 

H = 8th from start and 19th from end

E = 5th from start → 22 from end

Code = 19 × 22 = 418

Similarly, for GO

G = 7th from start and 20 from end

O = 15th from start and 12 from end

Code = 20 × 12 = 240

Now, we need to find the code of SHE.

S = 19th from start and 8th from end

H = 8th from start and 19th from end

E = 5th from start and 22nd from end

8 × 19 × 22 = 3344
