M % N means M is son of N.
M – N means M is wife of N.
M ÷ N means M is aunt of N.
M + N means M is sister of N.
M × N means M is father of N.

6. Which of the following means P is the grand father of D?
1)  N × P + D ÷ I + K 2)  P × N + I ÷ D + K 3)  D × P + N ÷ K + I 4) D % P + N ÷ I + K 5) None of these

7. Which of the following statements proves that there are two males in the family?
1)  A × J + K ÷ T 2)  M × T + G % L 3)  G ÷ A × Q + E 4)  L + P ÷ R + C 5) None of these

1)  I + K ÷ P + S 2)  P × I + K % S 3) P × J – K × S 4) R – S × P % X 5) None of these

9. Who prepares gulab jamun?
1)  Om 2)  Varun 3)  Rohit 4)  Tanisha 5)  Pawan

10. Who among the following gifts sweets to poor peoples?
1)  Om 2)  Pawan 3)  Tanisha 4)  Sahil 5)  Rohit

1.2; All cars are petrol + No petrol is a bus (A + E = E)= No
car is a bus + all buses are cycles (E + A = O)= Some
cycles are not cars. Hence I does not follow. But No
petrol is a bus + All buses are cycles = Some cycles
are not petrol. This leaves us with the possibility of II.

2.5; A + E = E So, I follows we also get some cycles
are not Cars. This leaves the possibility of II

3.2; I + A = I. Hence, some white are pagers + All
pagers are fax = some white are fax. This leaves
us with the possibility of II.

4.1; Some motors are machines (I) - No machine is a triangle
(E) = I + E = O = Some motars are not triangles. Hence,
Conclusion I follows Again, No generators is a motor
(E) + Some motars are machines (I) = E + I = O = Some
machines are not generators. Hence conclusion II does
not follow.

5.4; Some motars are machines (I) + No machine is a triangle
(E) = (I) + (E) = O = Some motars is a triangles. Hence,
conclusion I does not follow. Again, No generator is a
motor (E) + Some motars are machines (I) = E + I = O =
Some machines are not generators. Hence, conclusion
II does not follow.

7.5; None of the options proves that how many males in a family.
