15.
If all the missing seats filled as per the given conditions, which political

a) BJP
b) Congress
c) BSP
d) SP
e) AAP
Solutions:
1.
C) Let a child completes
4x units of work in one day, then,
In 20 days total units of work = 80x and
3 men, 2 women and 1 child can complete = (3 * 5x +
2 * 3x + 4x) units/day = 25x units/day
Total time taken by them to complete work A =
80x/25x = 16/5 days
Similarly, Time taken by 1 man, 3 women and 2
children to complete work D
= 15/(3 + 6 + 2) days = 15/11 days
Therefore Required % = {[(16/5) – (15/11)]/(15/11)}
* 100 = 404/3%
2.
B) Total time taken by a
man and a women to Complete work C = (6 * 21)/(8 + 7) = 126/15 days
Total time taken by 3 women and a child to complete
work E = (16 * 3)/(3*4 + 3) = 16/5 days
Therefore required ratio = 21 : 8
3.
D) Let child completes 3x units in one day
So, in 16 days he will complete = 16×3x= 48 x units
In 3 days (6x + 4x + 3x) unit will be completed
In 9 days 13x ×3 unit will be completed
On 10th day 3x more units will be completed by child
Remaining 6x units will be completed by man on 11th
day
4.
B) Share of man in completing work B = 4500/9 * 4
= 2000
Share of man in completing work D = 1800/6 * 3 = 900
Required % = (2000 – 900)/900 * 100 = 1100/9% = 122
2/9%
5.
E) Time taken by women to complete work C = (21 *
6)/7 = 18 days
Time taken by man to complete work D = (15 * 1)/3 =
5 days
Required % = (18 – 5)/5 * 100 = 13 * 20 = 260%

Due to share value changes the maximum loss is 10
for the month of December.
7.
A) The greatest percentage change in any share
was recorded for share L for the month of August viz
(50 – 40)/40 * 100 = 25%
8.
D)
9.
A) From the table given in sol 6 we can observe
that the individuals highest gain is 10.
10.
A) The greatest absolute change in the market
value is 20 ie in the month of September of the share of I = 115 – 95 = 20
11.
B) First of all, before solving this question we
should consider the following conditions in our mind:
1. Missing place values must not be more than 10% of total of a
particular state.
2.
Missing place values are least values of
particular state.
3.
And for this particular question, we should
keep BJP's seats maximum after fulfilling 1 & 2 condition.
Now, from the given information, we get
The total number of seats in UP = 290
Seats won by BJP and AAP in UP together = 290 – (90
+ 82 + 65) = 53
Check
conditions:
1. Maximum seats can be won by BJP in UP = 10% of
290 = 29 seats, therefore AAP would win 24 seats.
2. Both parties won least number of seats in comparison
to the other parties in UP
Similarly, in Manipur
Total number of seats in Manipur = 260
Seats won by BJP and Congress = 260 – (120 + 25 +
78) = 37
Check
conditions:
1. Maximum chances of BJP to win seats is 10% of 260
= 26
2. Now go through the second condition, which is not
satisfying the result of 1st condition because in Manipur SP has 25 seats, so
BJP can win maximum 24 seats, therefore Congress will get 13 seats.
Now, both have won least number of seats in Manipur
in comparison to others.
As per the question,
Maximum number of seats occupied by BJP in all
states = (29 + 100 + 24 + 58 + 52) = 263 seats
And as given, the total number of seats in all the
states = (290 + 300 + 260 + 210 + 270) = 1330
Therefore required % = 263/1330 * 100 = 19.77% ≈ 20%
12.
D) Consider the conditions as previous question,
we get
In UP, AAP gets 29 seats
Similarly
In MP, Total number of seats = 300
AAP and BSP seats together in MP = 300 – (100 + 65 +
75) = 60
Therefore, from the 1st condition 10% of 300 = 30
Now, check weather 30 is more than any other party
in the same state, if no than maximum possibility of AAP to get seats in MP is
30. Therefore, BSP will also get 30 seats.
In Punjab,
Total number of seats = 210
Seats won by AAP and BSP together = 210 – (58 + 54 +
61) = 37
Here, 10% of 210 = 21 Hence, there is possibility
that 21 seats won by AAP and 21 seats won by BSP
Maximum possible no. of seats won by AAP = 29 + 30 +
120 + 21 + 38 = 238 seats
And The maximum no. of seats won by BSP = 65 + 30 +
78 + 21 + 108 = 302 seats
Required difference = 302 – 238 = 64 seats
13.
D) As the question asks for the average seats of
Congress in all the states but in state Goa the seats of Congress is not
definitely known, so the average is also not determined.
14.
D) As per the question,
Total seats of SP = 270
SP seats in Goa = 270 – (82 + 75 + 25 + 61) = 270 –
243 = 27
Similarly, Congress seats in Goa = 260 – (90 + 65 +
54) = 260 – 209 = 51
But the maximum possible seats of congress in Goa =
10% of 270 = 27
So, 51 – 27 = 24 seats must be of Manipur.
Now, Total number of seats of Others' in Goa = 270 –
(52 + 27 + 38 + 27 + 108) = 270 – 252 = 18 seats
Hence, 18 seats of others parties are included in
Goa.
15.

conditions, we get

Total no. of seats won by Congress = 90 + 65 + 24 +
54 + 27 = 260
Total no. of seats won by AAP = 29 + 30 + 120 + 21 +
38 = 238
Total no. of seats won by SP = 82 + 75 + 25 + 61 +
