Question 1: Average age of A and B is 24 years and average age of B, C and D is 22 years. The sum of the ages of A, B, C and D is: . [Bank P.O. 1992]
(a) 90 years
(b) 114 years
(c) 96 years
(d) Data inadequate
Answer: A+B = (24 χ 2) = 48 and B + C + D = (22 χ 3) = 66
With this data, we can not find A + B + C + D.
So, the data is inadequate.
Question 2: A train travelling at a speed of 75 mph enters a tunnel miles miles long. The train is mile long. How long does it take for the train to pass through the tunnel from the moment the front enters to the moment the rear emerges?

(a) 21 days
(b) 14 days
(c) 42 days
x = 42
time = 42 days
Question 4: In a class of 52 students, the number of boys is two less than the number of girls. Average weight of the boys is 42kg, while the average weight of all the 52 students is 40 kg. The average weight of the girls is
(a) 37.25 kg
(b) 35.148 kg
(c) 38.148 kg
(d) 39 kg
(e) None of these
Answer: Let the numbers of boys and girls be (x - 2) and x, respectively.
x + (x - 2) = 52
2x = 54
x = 27
Number of girls = 27 - 2 = 25
Now, average weight of girls =
= 38.148 kg
Question 5: The blood groups of 200 people is distributed as follows: 50 have type A blood, 65 have B blood type, 70 have O blood type and 15 have type AB blood. If a person from this group is selected at random, what is the probability that this person has O blood type? (S.B.I 2005)
Answer: We construct a table of frequencies for the the blood groups as follows
We use the empirical formula of the probability
P(E) = 70 / 200 = 0.35
Question 6: if x:y = 1:3, then find the value of

Question 7: About the number of pairs which have 16 as their H.C.F. and 136 as their L.C.M., we can definitely say that : .[Cal. 1990]
(a) only one such pair exists
(b) many such pairs exist
(c) only two such pairs exist
(d) no such pair exists
Answer: H.C.F. of two numbers divides their L.C.M. exactly. Since 16 is not a factor of 136, it states that there does not exist any pair of numbers with H,C.F. 16 and L.C.M. 136.
Question 8: Pipes A and B can fill a tank in 5 and 6 hours respectively. Pipe C can empty it in 12 hours. If all the three pipes are opened together, then the tank will be filled in: (BANK P.O 1998)

The tank will be full in HRS.
Question 9: In a race of 200 m, A can beat B by 31 m and C by 18 m. In a race of 350 m, C will beat B by: ( S. B. I 2008)
(a) 5 m
(c) 15 m
(d) 25 m
Answer: A : B = 200 : 169.
A : C = 200 : 18
= 182 : 169.
When C covers 182 m, B covers 169 m.
When C covers 350 m, B covers m = 325 m
C beats B by (350 - 325) m = 25 m.
Question 10: What day was it on 2nd may 2010?
Answer: 2nd may 2010 = (2009 years + period from 1.01.2010 to 2.05.2010)
Counting odd days:
Numbers of odd days in 2000 = 0
Numbers of odd days 9 years = (2 leap years + 7 ordinary years) = (2 × 2 + 7 × 1) = 11 odd days = 4 odd days.
Total Odd day in 2009 year = (0 + 4) = 4 odd day
Jan Feb Mar Apr May
31 + 28 + 31 + 30 + 2 = 122 days
⇒ 122 days = (17 weeks + 3 day) = 3 odd day
∴ Total number of days = (3 + 4) = 7.
Hence, the required day is Sunday.

(e) Both 1 and 2 follow
Answer: The first premise is an I type proposition. So, the middle term 'angels' forming the predicate is not distributed. The second premise is an A type proposition. So, the middle term 'angels' forming the predicate is not distributed. Since the middle term is not distributed even once in the premises, no definite conclusion follows.
