| Manipulate the symbol and find the missing number. |
| If \[3*6=18\] |
| \[4*7=22\] |
| \[9*1=20\] |
| then, \[5*2=?\] |
A) 14
B) 7
C) 10
D) 3
Correct Answer: A
Solution :
Let us replace the * sign by the sign of addition'+'. Thus, \[(3+6)\] \[\Rightarrow \] \[9=18\] \[(4+7)\] \[\Rightarrow \] \[11=22\] \[(9+1)\] \[\Rightarrow \] \[10=20\] We see that right hand side is double the left hand side thus, \[(5+2)\] \[\Rightarrow \] \[7=14\] Our required missing number is 14.
