Question 1: N?S,S@P ,P£M.
Conclusion : I. S@M, II. P©N
a) If only one conclusion I follow
b) If only one conclusion II follow
c) If either conclusion I or II follow
d) If neither conclusion I or nor II follow
e) If both conclusions follow
1) Answer (D)
Solution:
Statements : N < S ; S > P ; P $\leq$ M
Conclusion :
I. S@M : $S>M$ : false
II. P©N : $P=N$ : false
Thus, neither conclusion I or nor II follow.
=> Ans – (D)

2) Answer (D)
Solution:
Statements : J = P ; P $\geq$ N ; J $\leq$ H
Combining above statements, we get : $H\geq J=P\geq N$
Conclusion :
I. J©N : $J=N$ : false
II. H@P : $H>P$ : false
Thus, neither conclusion I or nor II follow.

3) Answer (B)
Solution:
Statements : Z > D ; F = D ; F $\geq$ G
Combining above statements, we get : $Z>D=F\geq G$
Conclusion :
I. D©G : $D=G$ : false
II. Z@G : $Z>G$ : true
Thus, only one conclusion II follow.

b) H=85★100★M
c) H=85#100#M
d) H=(85#100)★M
e) None of these
6) Answer (D)
Solution:
H = 85% of M
=> $H = \frac{85}{100} \times M$
$\therefore$ H = (85 # 100) ★ M
=> Ans – (D)
Question 7: salary of Mr X (S1) is more than 40% of Mr .Y’s salary(S2) BY Rs 8000.
a) S1=[S2★(40@100)]#8000
b) S1=[S2★(40#100)]@8000
c) S2=[S1★(40#100)]@8000
d) S2=[S1★(40@100)]#8000
e) None of these
7) Answer (B)
Solution:
S1 = 40% of S2 + 8000
=> $S1 = (\frac{40}{100} \times S2) + 8000$
=> $S1 = (S2 \times 40 \div 100) + 8000$
$\therefore$ S1 = [S2 ★ (40 # 100)] @ 8000
=> Ans – (B)
Question 8: Number of boys in (B) IN class is equal to one fourth of three times the number of girls (G) in the class

b) B=(3★G)@4
c) B=(3★G)#4
d) B=(3$G)#4
e) None of these
8) Answer (C)
Solution:
B = $\frac{1}{4} \times 3 \times$ G
=> $B = (3 \times G) \div 4$
$\therefore$ B = (3 ★ G) # 4
=> Ans – (C)
Question 9: Population of state M(P1) is less than half of population of state of N(P2) by 1,50,000
a) P2=(P1#2)$1,50,000
b) P1=(P2#2)@1,50,000
c) P1=(P2#2)$1,50,000
d) P2=(P2#2)$1,50,000
e) None of these
9) Answer (C)
Solution:
P1 = half of P2 – 1,50,000
=> P1 = $\frac{P2}{2}$ – 1,50,000
$\therefore$ P1 = (P2 # 2) $ 1,50,000
=> Ans – (C)
Question 10: Total age of 12 boys is X and the total age of the 13 girls is Y. What is the average age (A) of all the boys and girls together?

b) A=(X$Y)#25
c) A=(X@Y)★25
d) Cannot be determined
e) None of these
10) Answer (A)
Solution:
A = total age/total students
=> A = (X + Y) $\div$ (12 + 13)
=> A = (X + Y) $\div$ 25
$\therefore$ A = (X @ Y) # 25
=> Ans – (A)
