SYMBOLS AND NOTATIONS
The questions can be based on
Blood Relations
Mathematical Operations (or
Operator based questions)
1. Blood Relations
P x Q means P is the mother of Q
P + Q means P is the father of Q
P – Q means P is the son of Q
Which of the following means A is the Grandson of D ?
(1) A x C+D
(2) A +B+D
(3)D+B+A
(4) A-B-D
Explanation:A x C+D means A is the mother of C and C is the father of D Grandchild of AA+B+D means A is the father of B and B is the father of D. Hence D is the Grandchild of AD+B+A means D is the father of B and B is the father of A. Here A is the Grand child of D, but we don’t know whether he is the Grandson or Granddaughter of DA-B-D means A is the son of B and B is the son of D. Hence, A is the Grandson of D
2. Mathematical Operations
IF ‘+’ stands for ‘-‘ , ‘-‘ stands for ‘x’, ’x’ stands for ‘÷’and ‘÷’stands
for ‘+’then what is the value of 56x7÷13-11+15-8÷2-7?
(1)30
(2)45
(3)60
(4)90
Explanation:
Changing the symbols as given in the problem the above expression is
56÷7+13x11-15x8+2x7
Solving the BODMAS rule, we get 8+143-120+14=165-120=45
