Answer 1

Write your age = 10

Multiply it by 7 = 10 x 7 = 70

Again multiply the answer by 13 = 70 x 13 = 910

  70
x 13  
 210  (70 x 3)
 700  (70 x 10)
 910

Multiplying again that answer by 11 = 910 x 11 = 10010

 910
 x 11
  910    (910 x 1)
 9100   (910 x 10)
10010

Yes. I can find my age in final answer, my age appears two times in the answer.
