completes W1 in as many days as he takes to
complete W4. Ratio of time taken by C to D to
complete W1 is 4:5. B and C take the same

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)

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)
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)
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)
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)
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)
