Q. If in coded language
23 = 10
72 = 63
65 = 66
84 = 96
Then
97 = ?

• 2x(2+3)=10
  7x(7+2)=63
  6x(6+5)=66
  8x(8+4)=96
  9x(9+7)=144
• 10 years agoHelpfull: Yes(87) No(0)
• 23=2*(2+3)=10
  72=7*(7+2)=63
  65=6*(6+5)=66
  84=8*(8+4)=96
  similarly
  97=9*(9+7)=144

• the answer is 144
  2+3=5 which is multiplied by 1st digit of 23 i.e 2 which will gives us 10
  so, 9+7=16 16*first digit of number i.e.9 =144

• special tricks by RAHUL SAHA(HALDIA HIT)
  23=2^2+(2*3)=10
  72=7^2+(7*2)=63
  65=6^2+(6*5)=66
  84=8^2+(8*4)=96
  97=9^2+(9*7)=144 ANS 144

• 23=10 means 2+3=5and 5*2=10
  72=63 means 7+2=9 and 9*7=63
  so on
  97=144
• 10 years agoHelpfull: Yes(0) No(1)
• 2+3*2=10
  7+2*7=63
  6+5*6=66
  8+4*8=96
  9+7*9=144
  so 97=144

• first digit*(sum of first and second digit)=Coded no.
  23=10 -> 2*(2+3)=10
  72=63 -> 7*(7+2)=63
  65=66 -> 6*(6+5)=66
  84=96 -> 8*(8+4)=96
  97 -> 9*(9+7)=144
  So Ans=144
