The correct option is A 21
TTT = 100T + 10T + T
= T(111)
= T(37 × 3)
Here, we have
37×3×1=111
37×3×2=222
37×3×3=333
37×3×4=444
37×3×5=555
37×3×6=666
37×3×7=777
37×3×8=888
37×3×9=999 or 37×27 = 999
Since, ME x YE = TTT
Hence, we can take
37 x 27 = 999
M = 3, Y = 2, E = 7 and T = 9
Or M = 2, Y = 3, E = 7 and T = 9
Y + M + E + T
= 2 + 3 + 7 + 9 or 3 + 2 + 7 + 9
= 21
