120. 6 persons standing in queue with different age group, after two years
their average age will be 43 and seventh person joined with them. hence
the current average age has become 45. find the age of seventh person?

Solution: Here the question appear as an easy one, but carried a lot of
unwanted sentences and unwanted datas(i dint mention above) in exam which
may confuse u on solving technique.

Let x be current average age of first 6 persons in queue and current age
of seventh person be y. Then 6x will become the sum of those 6 persons
age.

Now, let compute the sum of those 6 persons after two years, 6x+12 (as
each and individual increase their age by 2). hence its average become
(6x+12)/6 = 43 (give in question itself).

So now we can compute x from above equation. (x = 41, 6x = 246)

Let now we compute y, ((6x+y)/7) = 45, as we have value of x, compute y.

Ans: 69


121. Horse started to chase dog as it relieved stable two hrs ago. And
horse started to ran with average speed 22km/hr, horse crossed 10 mts road
and two small pounds with depth 3m, and it crossed two small street with
200 mts length. After traveling 6 hrs, 2hrs after sunset it got dog.
compute the speed of dog?

Ans: As we have speed and travel time of horse, we can get distance
travelled by it...

Hence d = 22*6 = 132km,

Exactly this 132km was travelled by dog in 8 hours (as it started two
hours earlier).

Hence speed of dog = 132/8 = 16.5km/hr

Ans:16.5km/hr.

their average age will be 43 and seventh person joined with them. hence
the current average age has become 45. find the age of seventh person?

Solution: Here the question appear as an easy one, but carried a lot of
unwanted sentences and unwanted datas(i dint mention above) in exam which
may confuse u on solving technique.

Let x be current average age of first 6 persons in queue and current age
of seventh person be y. Then 6x will become the sum of those 6 persons
age.

Now, let compute the sum of those 6 persons after two years, 6x+12 (as
each and individual increase their age by 2). hence its average become
(6x+12)/6 = 43 (give in question itself).

So now we can compute x from above equation. (x = 41, 6x = 246)

Let now we compute y, ((6x+y)/7) = 45, as we have value of x, compute y.

Ans: 69


181) Horse started to chase dog as it relieved stable two hrs ago. And

and two small pounds with depth 3m, and it crossed two small street with
200 mts length. After traveling 6 hrs, 2hrs after sunset it got dog.
compute the speed of dog?

Ans: As we have speed and travel time of horse, we can get distance
travelled by it...

Hence d = 22*6 = 132km,

Exactly this 132km was travelled by dog in 8 hours (as it started two

.A hare and a tortoise have a race along a circle of 100 yards diameter. The tortoise goes in one direction and the hare in the other. The hare starts after the tortoise has covered 1/5 of its distance and that too leisurely. The hare and tortoise meet when the hare has covered only 1/8 of the distance. By what factor should the hare increase its speed so as to tie the race?

a. 8

b. 37.80

c. 5

d. 40

ANS :b

hint:in the first case time taken by hare to reach 1/8 of distance and tortoise to cover 1-1/5-1/8=27/40 of distance is same.in the second case time taken by tortoise to reach 1/8 of distance and hare to cover 7/8 of distance is equal.so equate these 2 eqns to get the increase in speed by hare!
let x be total distance
in first case
(27/40)x/speed of tortoise=(1/8)x/speed of hare
in 2nd case
(1/8)x/speed of tortoise=(7/8)x/new speed of hare
divide eqn 1 by 2 to get increase in speed by hare!

14.Alok and Bhanu play the following min-max game. Given the expression N = 9 +X + Y– Z where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu
would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal
strategies, the value of N at the end of the game would be
a. 27
b. 18
c. 20
d. 0.0

ANS:c
hint:just trial and error,the values taken by alok are 7,9 and 9(check yourself!)in our aptitude exam(cusat) the same question was asked with 9 changed as 7.in that case just remember the formula x+y-z=11! and apply!


15.A person drives with constant speed and after some time he sees a milestone with 2 digits. Then travels for 1 hours and sees the same 2 digits in reverse order. 1 hours later he sees that the milestone has the same 2 digits with a 0 between them. What is the speed of the car?
a.54.00 mph
b.45.00 mph
c.27.00 mph
d.36.00 mph
ANS: b
s=speed
"Then travels for 1 hour and sees the same 2 digits in reverse order."
10x + y + 1s = 10y + x
10x - x + s = 10y - y
9x + s = 9y

1 hours later he sees that the milestone has the same 2 digits with a 0 between them."
10y + x + s = 100x + y
10y - y + s = 100x - x
9y + s = 99x

Rearrange the above two equations for elimination
9x - 9y + s = 0
-99x+9y + s = 0
----------------adding eliminates y
-90x + 2s = 0
2s = 90x
s = 45x
x has to equal 1, then s = 45 mph (If x=2 and s=90 mph, when added to
a two digit milestone, could not be at another two digit milestone.)
