a) Quantity I < Quantity II

b) Quantity I > Quantity II

c) Quantity I ≥ Quantity II

e) Quantity I = Quantity II or relationship cannot be established

Directions (1-5):

Quantity I:

According to the question,

One day work of Nithya and Priya together = (1/15) + (1/18)

= 11/90

Thus number of days taken by Kalai to complete the work = (90/11) * (11/5)

= 18 days

Quantity II:

Efficiency ratio of A and B = 600: 500 = 6: 5

Time ratio of A and B = 5: 6 = 5x : 6x

According to the question,

1/5x + 1/6x = 11/120

11/30x = 11/120

x = 4

Number of days taken by B alone = 6 * 4 = 24 days

Quantity III:

(P+ Q)’s one day work = 3/20

(Q+R)’s one day work = 1/6

(R+S)’s one day work = 1/10

R’s one day work = 1/10 – 1/30 = (3 – 1)/30 = 2/30 = 1/15

Q’s one day work = 1/6 – 1/15 = (5 – 2)/30 = 3/30 = 1/10

P’s one day work = 3/20 – 1/10 = (3 – 2)/20 = 1/20

P can complete the work in 20 days

Quantity I:

Let CP = 100

Then MP = 150

Now SP = (90/100) * 150

= 135

Thus profit percentage = 35%

Hence required amount = 100 * 40 * 35/100

= Rs.1400

Quantity II:

Let us take marked price of an article be Rs. X

According to the question,

x * 90/100 * 120/100 * 80/100 = 864

x = 864 * 100/90 * 100/120 * 100/80

x = Rs. 1000

Quantity III:

Profit ratio of A and B = (4x * 3+ 4x * 1/4 * 9): (5x * 12)

= (12x + 9x): 60x

= 21x: 60x

= 7: 20

Let us take the total profit be x

A’s share in the total profit = 3500

x * (7/27) = 3500

=> x = 500 * 27 = Rs.13500

Quantity I: 6 hrs

Quantity II:

Original speed = 48/4 = 12 km/hr

New speed = 12 * 120/100 = 14.4 km/hr

Required time = 72/14.4 = 5 hrs

Quantity III:

A + B + C = 8hrs

A + C = 12hrs

LCM of (8,12) = 24

Number of units of water filled by A, B and C together = 24/8 = 3 units

Number of units of water filled by A and C together = 24/12 = 2 units

(i.e.) Number of units of water filled by B = 3 – 2 = 1 units

Number of units of water filled by C in one hour = x units

Number of units of water filled by A in one hour = 33(1/3)% of x = x/3

A + C = 2 units

x + x/3 = 2

x = 1.5 units

Water filled by B and C together = 1 + 1.5 = 2.5 units

Time = 24/2.5 = 9.6 hrs

Quantity I:

Number of ways = (6C2 * 6C2) + (6C3 * 6C1) + (6C4)

= [(6 *5 /1 * 2) * (6 * 5/1(1 * 2)]+ [(6 * 5 * 4/1 * 2 * 3) * 6] + (6 * 5/1 * 2)

= (15 * 15) + (20 * 6) + 15

= 225 + 120 + 15

= 360

Quantity II:

C’s one day work = 3/16 – 7/48

= (9 – 7)/48

= 2/48

= 1/24

(A + B)’s one day work: C’s one day work = 7/48: 1/24

= 7: 2

C’s share = 2/9 of total wage = 200

Total wage = (200/2) * 9 = Rs.900

Quantity III:

Let the marked price be Rs. x

Discount = 15% of Rs. x

C.P. = (x – 15% of x) = Rs. 17x / 20

Then 15% of 17x / 20 = 1955 – 17x / 20

51x/400 + 17x/20 = 1955

x = 2000

Discount received by retailer = (15% of 2000) = Rs.300.

Quantity I:

According to the question,

45 * x = 25 * 36 + 20 * 22.5

45x = 900 + 450

x =1350/45 = 30 yrs

Quantity II:

Let x year ago, the ratio of Rahul and Praveen’s ages was 3: 5

(40 – x)/(60 – x) = 3/5

=> 200 – 5x = 180 – 3x

=> x = 10 years

Quantity III:

(4x + 12)/(5x + 12) = 7/8

32x + 96 = 35x + 84

3x = 12

x = 4

Difference in their ages = (5x – 4x) = x = 4 years

Directions (6-10):

LCM of number of Days for work A done by X, Y, Z alone is 120, consider this is the total parts of work.

Efficiency of work per day for X, Y, Z is in the ratio of 10:15:6

For the first two days 50 parts of total work has completed

Remaining 70 parts are done by X and Z in alternative days. so every two days,16 parts completed

After (8 days) 4 full cycle, 4* 16=64 parts completed 6 parts remained

X again start the work and completed in 3/5 days

So the work completed in 10 3/5 days

LCM of Days for work C is done by X, Y, Z alone is240, consider this is the total part of work.

Efficiency of work per day for X, Y, Z is in the ratio of 10:15:6

Work done by X and Z individually is 60 and 180 parts respectively

X completed its 60 parts in 60/10= 6 days

Z completed its 180 parts in180/6= 30 days

The difference between the number of days is 24.

Statement I: we cannot compare work A and work E and solve it.

Statement II:  From the chart, LCM of number Days for work E done by X, Y, Z alone is 90, and Efficiency is in the ratio of 10: 15: 6 for X: Y: Z Respectively and Q can complete the work in 18 days.

By combining, statement II and Statement III,

Total parts per day* Number of Days = Total Parts of Work

(5+P) 9= 90

P=5 parts per day

So P alone can complete the work in 18 days.

LCM of number of Days for work A done by X, Y, Z and R alone is 120, consider this is the total part of work A

The Efficiency of R is 12 parts per day

S takes ¼th of total time by Z for work C= 10 days

LCM of Days for work B done by X, Y, Z and S alone is 150, consider this is the total part of work B

The Efficiency of S is 15 parts per day

LCM of Days for work E done by X, Y, Z alone is 90, consider this is the total part of work E

For every two days they completed 27 parts

After the 3 full cycles (6 days) they completed 27*3 = 81 parts, reaming 9 parts done by S in 3/5 of a Day

So the total work is completed in 6 3/5 days.

Quantity I:

LCM of Days for work E done by X, Y, Z alone is 90, consider this is the total part of work E

Efficiency of work per day for X, Y, Z is in the ratio of 10: 15: 6

Total parts per day* Number of Days = Total Parts of Work

6*5 + 10 XD= 90

XD= 6

So total number of days is 11 days

Quantity II:

LCM of Days for work B done by X, Y, Z and S alone is 150, consider this is the total part of work B

Efficiency of work per day for X, Y, Z is in the ratio of 10:15:6

Total parts per day* Number of Days = Total Parts of Work

15*5 + 6 * ZD= 150

ZD = 12.5, So total number of days is 17.5 days
