Ans. C

G A T E + E C E => 

  • E + E = 14 + 14 = 28 => 1A
    • Sum = A
    • Carry = 1
  • T + C + carry = 17 + 12  + 1 = 30 => 1C
    • Sum = C
    • Carry = 1
  • A + E + carry = 10 + 14 + 1 = 25 => 17
    • Sum = 7
    • Carry = 1
  • G + 1 = 16 + 1 = 17
    • Sum = T

G A T E + E C E = T 7 C A
