A) Rs.4 profit
B) Rs.2 loss
C) Rs.2 profit
D) Rs.4 loss
E) None of these

SOLUTIONS:

Option D
Solution:
Prob. of 1st winning = 2/7, so not winning = 1 – 2/7 = 5/7
Prob. of 2nd winning = 3/5, so not winning = 1 – 3/5 = 2/5
So required prob. = 2/7 * 2/5 + 3/5 * 5/7 = 19/35

Option A
Solution:
There are 52 cards, out of which there are 12 face cards.
So probability of 2 face cards = 12C2/
52C2 = 11/221

Option B
Solution:
Let original length = l, breadth = b, so area = lb
When l and b increased by 1:
(l+1)(b+1) = lb + 27
Solve, l + b = 26
When l increased by 1, b decreased by 1:
(l+1)(b-1) = lb – 7
Solve, l – b = 6
Now solve both equations, l = 16, b = 10
Perimeter = 2(16+10)=52m

Option A
Solution:
Volume of water in the tank is 80*60*6.5=31200m^3
Then Volume of water flown in 1hr is 20*1000(in meter)*20/100*20/100(in
meter)=800m^3
Time taken=31200/800=39hrs

Option A
Solution:
S=D/T
Here we have two speeds. We get 2 equations as.
250/1hr = C+B—-1 (Travelling in opposite direction, speed must be added ie
C+B)
250/5hr = C-B—-2 (Travelling in same direction, speed to be subtracted. ie C-
B)
solving 2 eqn C=150km/hr.

Option A
Solution:
Speed ratio 40:37 1/2==>40: 75/2==>80:75 ie 16:15
ratio diff between speed is 1[16-15]
1 ===> 200 (more distance)
[16+15]31 ===>?
31*200=6200km.

Option D
Solution:
Let the number of failed students be x
Number of passed students = 4x
So total number of students was 5x
From the given data
f total number of students be 5x – 35
(5x-35)/x+9=3/1
x = 31
Total number = 31×5 = 155

Option C
Solution:
8M+3B=4(1M+1B)
8M+3B=4M+4B
4M=B
B:M=4:1

Option A
Solution:
profit …………….loss
+16 …………….. -8
———–0
8……………16
1 : 2
Therefore ,
price of watch sold at profit = (1/2) * 800 = Rs. 400
price of watch sold at loss = 2 * 800 = Rs. 1600
