1).c   2).a   3).d   4).a    5).c    6).c    7).b    8).a    9).d    10).c

Solution:
1). C) Total number of players playing Cricket in Institutes M and Q together
= 4600 ×[ (13+16) / 100] = 4600 × (29/100) = 1334

2). A) Number of players playing Cricket in Institute P =  4600 x (12/100) = 552 Number of players playing Volleyball in Institute P = 5400 x (15/100) = 810
Total number of players = 552 + 810 = 1362

3). D) Number of players playing Cricket in Institute S = 4600 x (20/100) = 920 Number Of players, playing Volleyball in Institute S = 5400 x (12/100) = 648
Reqd ratio = 920 : 648 = 115 : 81

4). A) Number of players playing Cricket in Institute N= 4600 x (10/100) = 460 Number of players playing Volleyball in Institute R = 5400 x (19/100) = 1026 Reqd Reqd ratio = 460 : 1026 = 230 : 513

5). C) Reqd % = [4600 × (16+14) × 100] / [5400 × (14+19)] %
= (4600 × 30 × 100) / (5400 × 33) = 77.44%

6). C) In the year 2012 for shop A
= 50/100 = (36 — CP) / CP
or, CP = 72 — 2CP       or, 3CP = 72
CP = Rs. 24
Now, CP of 1 book = Rs. 24
CP of 3470 books = 3470 x 24 = Rs. 83280

7). B) In the year 2014 for B
Profit % = (Profit / CP) × 100%  [ Profit = SP— CP]
or, 40 = (36800/CP) × 100
CP = Rs. 92000
[SP= CP + Profit]
SP = 92000+36800 = Rs. 128800

8). A) Percentage profit of Shop A in the year 2011 = 60% and in the year 2010 = 40%
Therefore required percentage increase = [(60-40) / 40] × 100 = (20/40) x100 =50%

9). D) In the year 2013, let the total selling price of Shop A = Total ,cost price of shop B = Rs. x.
Now, in 2013 for Shop B.
50/100 =  (SP— x) / x
or, x = 2 × SP - 2x
or, 3x=2 x SP
SP = 3x/2
Now, requited ratio
= SP of Shop A : SP of Shop B
= x : 3x/2 = 2 : 3

10). C) Percentage of profit of Shop A decreases from 2012 to 2014. So, statement (a) is incorrect.
Shop B earned, the lowest percentage of profit in the year 2015, not in 2011. So, statement (b) is incorrect

In the year 2014, percentage profit earned by Shop. A and B. are the same. So, statement (c) is correct.
