Total 15 questions(1 mark each) r given 30 mins with 1/4 -ve marking. All r objective.

If SCOTLAND = 12345678, SAT=453, DON=128, and SALT=3782 then C = ?SAT,DON,SALT are not the exact words that were given but similar .LOGIC : C is not ther in any of the words other than 'scotland' and also 6. so C = 6.
