Number of males who like only painting is equal
to the number of males who like only dancing.
So, the number of males who like only dancing
is =20
Number of females who like only dancing
is=20*100/80=25 which is equal to the number
of females who like only singing.

Detailed Solution:
Total eight people like both singing and dancing
but not painting which is one more than the
number of people who like both singing and
painting not dancing,
So, the total number of males who like both
singing and painting but not dancing is=7*4/7=4
and the total number of females who like both
singing and painting but not dancing is=7-4=3
Number of males who like both dancing and
painting is 4/2=2 which is equal to the number of
females who like both dancing and painting but
not singing.
Number of males like all three is 3.
Number of females like all three is =3*100/75=4
Number of females who like only dancing and
singing but not painting is 3.
So, the number of males who like only dancing
and singing but not painting is 8-3=5.
Number of females who like only painting is six
times the number of females who like both
dancing and singing but not painting
Number of females who like only painting
is=6*3=18
Number of males who like only painting is =38-

Detailed Solution:
1)
Height of cone is =6*2=12
So, 2X=12, X=6.
So, the length of the cuboid is 3*6=18
Height of cuboid is =14*114.28/100=16
So, the volume of the cuboid is=16*18*9=2592
So, the required difference is=2016 (C)
sиαρσnє🌱
2)
Radius of the circle is r.
So, we can say, 2*(22/7) *r*23=2024
Or, r=2024*7/(22*2*23)=14
So, the radius of the cone is 14.
So, 1/3*22/7*14*14*2X=576
Or, X=1.4
So, the length of the cuboid is =3 *1.4=4.2
Height of cuboid is=14*2=28
So, volume is =28*4.2*9=1058.4 (D)
3)
We can say, (22/7) *14*14*h=7392 [h=height of
the cone]
Or, h=12
Height of cylinder is =12 unit= height of the cone
So, the length of cuboid is=12*3/2=18
lateral surface area of the cuboid is=2*12*(9+18)
=648
Curved surface area of cylinder is= 2*(22/7)
*14*12=1056
So, the difference is=1056‒648=408 (B)
sиαρσnє🌱
4)
Side of the square is =√𝟓𝟕𝟔 = 24
Side of the cube is =24*(100-8.33)/100=22
Volume of cube is=22*22*22=10648
Volume of sphere= 4/3*(22/7) *6*6*6=905.14
Required sum is=10648+905.14=11553.14 (A)
5)
Length of cuboid is=9*4/1=36
Height of cone is=12*2=24
So, r^2=1232*3*7/22*24 [ r= radius of another
cone]
Or, r=7
So, slant height is = square root of (24^2+7^2) =25
Curved surface area is=550 (A)
2 918
1) If the height of the cone is double the radius of
the sphere and the height of the cuboid is
14.28% more than the radius of the Cylinder then

cuboid and the volume of the cone?
a) 2017
b) 2018
c) 2016
d) 2020

Rs.23 per unit is 2024. If the radius of the circle

a) 1236.2
b) 1453.6
c) 1256.4
d) 1058.4

Detailed Solution:
1.
Statement I –
Let Breadth of cuboid B is 3U
So, 3U * 5 + 5 * 8 + 8 * 3U = 158/2 = 79
Or, 39U = 79 – 40
Or, U = 1
Length, breadth, height of cuboid B is 5, 3, 8
respectively and breadth of cuboid A is 2 and
height and length of cuboid A is 3v and 2v
respectively.
So, we can calculate the volume of cuboid B i.e.,
5 * 3 * 8 = 120 but cannot calculate the volume
of cuboid A.
Statement II –
Total surface area of cuboid A is 88. But we
cannot calculate individual volume from it.
From both statements,
1st statement we get, breadth of cuboid A is 2
and height and length of cuboid A is 3v and 2v
respectively
So, we can say, 2 * (2 * 3v + 3v * 2v + 2v * 2) =
88
From this we get v = 2.
So, volume cuboid A = (2 * 2) * 2 * (3 * 2) = 48
Required difference = 120 – 48 = 72
So, using two statements we get the answer. (C)
sиαρσnє🌱
2.
Statement I –
Let age of D is x.
Age of E = x + 5, age of B = x + 5 – 14 = x - 9,
age of C = x – 9 + 2 = x - 7, age of A = x – 7 + 2
= x - 5
So, we cannot calculate the age of A.
Statement II –
The Ages of B and C are 8j and 9j.
Age of D = 9j + 7
Age of E = [9j + 7] * 6/5
So, we can say, [9j + 7] * 6/5 - 9j = 12
From this we get value j, from value j we
calculate age of E and C, from that we can
calculate age of A.
Statement II alone is sufficient. (B)
sиαρσnє🌱
3.
Statement I –
Let milk in A = 4x and milk in B = 2x.
Water in B = 2x * 1/2 = x = 10
So, milk in mixture A = 4 * 10 = 40
So, statement I is sufficient.
Statement II –
Difference of milk in mixture A and mixture C is
10 and the difference of water in mixture A and
B is 20. So, milk in A can be more or less. From
the statement we cannot calculate the amount of
milk in mixture A because there is no direct data
given. (A)
sиαρσnє🌱
4.
Statement I –
Speed of stream river S is 3 km/hr more than
river P.
Let the speed of stream river P = x, speed of
stream river S = x + 3.
But we cannot calculate the time taken by boat
A in river P to go 120 Km upstream. Because we
do not know the speed of boat A and speed of
stream river P.
Statement II –
2 x (22 + p) = 60
Or, p = 16/2 = 8
Speed of stream in river S = 8
So, we cannot get the answer from statement II.
But from both statement we can say, speed of
stream in river P = 8 – 3 = 5
Speed of boat B = [52 – (8 * 2)]/2 = 18 km/hr
So, speed of boat A = 18 + 2 = 20 km/hr.
We know the speed of boat A and the speed of
the stream in river P. so we can calculate the
answer. (C)
5.
Statement I –
Let the efficiency of P and Q is 6x and 5x.
So, time taken by P is 5x.
But from the given information we cannot
calculate the actual number of days taken by P.
Statement I alone is not sufficient.
Statement II –
Let P takes y days to complete the work and T
takes 3y to complete work.
R takes y + 5 days to complete the work.
So, we can say, 1/ (y + 5) + 1/3y = 1/6
From this we get y = 5, so P can complete the
work in 5 days.
Statement II alone is sufficient. (B)

d) Neither Statement I nor II is sufficient.
e) Either Statement I or II
2 918
Detailed Solution:
The Ages of A and B are 4x and 5x.
Age of C is 5x + Y.
According to the question, 4x + 5x + Y + 4 = 60,
or, 9x + Y = 56
So, 5x + Y + 4Y = 40, or, X + Y = 8
So, X = 6 and Y = 2
Ratio of age of A, B and C 24:30:32 = 12:15:16
Ratio of total amount of A, B and C is 12:15:16.
We can say 4 unit = 8000
Or, 1-unit = 2000.
Amount of A, B, C is Rs.24000, Rs.30000 and
Rs.32000 respectively.
So, M = 30000
A invest Rs.14000 in R% interest for 2 years.
So, 2800 = 14000 * 2 * R/100
Or, R = 10%
Let C invest Rs. F at R/2 = 5% rate of interest.
So, F * (1 + 5/100) ^2 – F = 2050
Or, 41F/400 = 2050
Or, F = 20000
So, C invest in business = 32000 – 20000 =
12000
B’s investment in business is maximum, so B
invest amount 12000 + 3000 = 15000
So, investment ratio = 10:15:12
So, [15 * P/37] = 3000
Or, P = 7400
B invests Rs.15000 in 2R% = 20% compound
interest in 2 years.
So, B’s interest amount is
= 15000 x (1 + 20/100) ^2 – 15000 = 6600 = I
sиαρσnє🌱
1.
Required sum of age is = 24 + 2 * 2 + 30 + 2/2 +
32 + 3 * 2/2 = 94 (C)
2.
A’s share of profit is = 7400 * 10/37 = 2000
C’s share of profit = 7400 – 2000 – 3000 = 2400
So, required difference = 2000 + 2800 – 2400 –
2050 = 350 (D)
sиαρσnє🌱
3.
B’s share of profit = 3000
B’s interest amount = 6600
Total selling price = 6600 * 110/100 + 3000 *
80/100 = 9660 (B)
