- 2x(2+3)=10
7x(7+2)=63
6x(6+5)=66
8x(8+4)=96
9x(9+7)=144 - 11 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 - 11 years agoHelpfull: Yes(22) No(1)

- 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 - 11 years agoHelpfull: Yes(1) No(0)

- 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
