if 20+15=24 and 64+13=42 then 11+28=?

• 20 + 15 = 24
  in this case we add the numbers like,
  2 + 0 + 1 + 5 = 8 then multiply by 3
  we get 24
  similarly for 64 + 13 = 42
  6 + 4 + 1 + 3 = 14
  multiply by 3 we get 42
  so for 11 + 28
  1 + 1 + 2 + 8 = 12
  multiply by 3 we get 36
  so 36 is the answer.

• i think ... in place of 64 it would be 62 ..
  20 +15=24 ( 2-0 =2 , 5-1= 4 )
  62+13=42 ( 6-2=4 ,3-1=2)
  then 11+28 = 06

• here 20+15=24 adding the numbers we get (2+0+1+5)*3=24
  64+13=42 " " (6+4+1+3)*3=42
  same 11+28=(1+1+2+8)*3=36(Ans)

• (2+0+1+5)*3=24
  (6+4+1+3)*3=42
  (1+1+2+8)*3=36
