The sports club in the university organized three major games viz: football, volleyball and basketball. The ratio of the number of students playing football and basketball only and those playing volleyball and basketball only is 2:3. The students playing all the three games are twice the number of students playing football and volleyball only.

Answers With Explanation

Solution 1

Punjab bank , bank returns during 2004-2005 = 7485/4361 = 1.72
bank returns during 2003-2004 = 6647/4353 =1.53
Therefore ,

The percentage increase = ((1.72 – 1.53) / 1.53 )* 100 = (0.19/1.53) * 100
(a) The percentage increase = 12.6 % approx

Solution 2

We do not need to actually calculate the loans offered by all banks.
10% hike in rate of Interest must have increased interest earnings by 10% than the earnings with interest rate before hike
It is sufficient to compare the earnings without hike which are equal to 100 / 110 *earnings during 2004- 2005

(D) Three banks have shown a decrease in loans offered.

Solution 3

a) total interest earnings by 5 banks during the year 2004 – 2005 = Rs. 21744 mn
Minimum interest rate charged by any bank = 11%
Maximum loan offered by banks = 21744 * 100/11 < Rs.200000 mn
Hence statement I is false.
b) Only Andhra bank has increased in interest earnings between 5% and 10% In the year 2004-2005
Statement (b) is false
c)Total interest expenses during 2004 – 2005 = Rs. 13603
Maximum interest rate on deposits = 8.5 %
Minimum deposits in 5 banks = 13603 * 100 /8.5
8001*20 > Rs.1600000 mn
Statement ( c ) is false
Hence (d) none of these 

Solution 4-6

Let the number of students playing football and basketball only be 2y. so the number of students playing volleyball and basketball only is 3y
The number of students playing basketball only is 14y – 20
Let the number of students playing football and volleyball only be x. so , the number of students playing all the three games is 2x
Now ,
2x = 3y +3
(2x/3 – 1 ) = y
X+2y +3y = 112
X+10x / 3 - 5 = 112
Thus we get x =27 and y = 17

The number of students playing only basketball = 14y – 20 = 218 hence
(b) is the right answer for Question 4

Let the number of students playing football be ‘a’ and those playing volleyball be ‘b’
a-b = x+1 = 28 ….. (1)
a+b = 366 ……………(2)
solving equation (1) and (2) weget ,
a=197 and b=169
Hence ( c ) is the right answer for Question 5

The number of students playing all the three games is 2x = 54 and those playing only football and basketball is 2y= 34 

Hence (E) is the right answer for Question 6.

Solution 7 - 9

From (iii) and (iv) 
P>S , P >Q , U >S
P/S < P/Q and P/S < U/S
Gives S > Q and U> P
Using (v) , (vi) and (vii) we get the following arrangement ,
T<Q<V<S<P<U<R
So T , Q , V , and S are AP, while S , P , U and R in GP

From (ii) and (iii),
R/U = U/P = P/S = P/Q - P/S = U/S – P/Q ……… ( i )
P/Q = 2P /S and U/S = 3P/S
U = 3P
U/P = 3
So the common ratio of the geometric progression is 3
R=1080 , U= 360 , P= 120 AND S= 40

Substituting values of P and S in equation (i)
120/Q – 3 = 3
Q=20

Since 

S-Q = 20 = 2d , where d is the common difference of the four numbers is arithmetic progression
T= 10 , G= 20 and V = 30
The required arrangement is 10 , 20 , 30 , 40 , 120 , 360 , 1080

Solution 10

Let T be the total marks of the ‘n’ students originally, then T/n = 35 but actually T+10 / n = 36
Which gives n = 10 

Hence ( c) is the correct answer.
