Detailed Solution: (6 to 10)
Total number of vacancies in both the
Companies together = 14,400
Number of vacancies in company X = 14,400 ×
5/12 = 6000
Number of vacancies in company Y = 14,400 ×
7/12 = 8400
Vacancies for male in company X = 6000 ×
70/100 = 4200
Vacancies for female in company X = 6000 –
4200 = 1800
Vacancies for male in department P in company
X = 4200 × 3/5 = 2520
Vacancies for male in department Q in company
X = 1/8 × (4200 – 2520) = 210
Vacancies for male in department R in company
X = 7/8 × (4200 – 2420) = 1470
Vacancies for female in department Q in
company X = 1800 × 24/100 = 432
Vacancies for female in department P in
company X = 5/8 × (1800 – 432) = 855
Vacancies for female in department R in
company X = 1800 – 432 – 855 = 513
Vacancies for male in company Y = 8400 ×
80/100 = 6720
Vacancies for female in company Y = 8400 –
6720 = 1680
Vacancies for male in department P in company
Y = 6720 × 65/100 = 4368
Vacancies for male in department R in company
Y = 1470 × 12/10 = 1764
Vacancies for male in department Q in company
Y = 6720 – 4368 – 1764 = 588
Vacancies for female in department P in
company Y = 4368 × 25/100 = 1092
Vacancies for female in department Q in
company Y = 1/4 × (1680 – 1092) = 147
Vacancies for female in department R in
company Y = 3/4 × (1680 – 1092) = 441
sиαρσnє🌱
6.
The total number of female vacancies in the
department P in both the Company X and Y
together = 855 + 1092 = 1947
Hence, the required answer = 1947 (B)
7.
Vacancies for male in department R in company
X = 1470
Vacancies for male in company X = 4200
So, the required percentage = 1470/4200 × 100
= 35%
Hence, the required answer = 35% (D)
8.
Total of male and female vacancies in
department Q = 588 + 147 = 735
Total of male and female vacancies in
department R = 1764 + 441 = 2205
Hence, the required ratio between them =
735:2205 = 1:3
Hence, the required answer = 1:3 (C)
9.
Average number of female vacancies in
department R in both companies together = (513
+ 441)/2 = 477
Average number of male vacancies in
department Q in both companies together =
(210 + 588)/2 = 399
Thus, the required difference between them =
477 – 399 = 78
Hence, the required answer = 78 (B)
10.
Vacancies for female in department Q in
company Y = 147
Total vacancies for female in company Y = 1680
So, the required percentage = 147/1680 × 100 =
8.75%
Hence, the required answer = 8.75% (B)

Total cost of decorating 3M/2 sheets buys by P
is 181.25% more than that of 0.6M sheets buys
by Q.
So, Ratio of total cost of decorating 3M/2 sheets
buys by P is 181.25% more than that of 0.6M
sheets buys by Q = 45/16
Total area decorated by P = 3M/2 x (K + 2) x (K
+ 2)
Total area decorated by Q = 0.6M x (K – 2) x (K
– 2) x 2 [both sides]
Now,
[3M/2 x (K + 2) x (K + 2)] / [0.6M x (K – 2) x (K –
2) x 2] = 45/16
(K + 2)^2 / (K – 2)^2 = 9/4
(K + 2) / (K – 2) = 3/2
2K + 4 = 3K – 6
Value of K = 10 (B)

Value of M = 10
Now,
18 x N x 12 x (10 – 4) = 20736
Value of N = 16 (D)

Detailed Solution: (1 to 3)
Let radius of circle drawn on longest side of
triangle = r cm
Circumference of semi-circle = πr + 2r
Now,
3 x r + 2r = 85/2
Value of r = 17/2 cm
So, longest side of the triangle = 2r = 2 x 17/2 =
17 cm
Each side of triangle is a natural number, so
there is one possible triplet that includes 17 as
largest number is (8, 15, 17).
So, other two sides are 8 cm and 15 cm
If (b – 2) = 8
Value of b = 10
Then (a + 3) = 15
Value of a = 12
But area of square = 3 x [b – a], so b > a
So, (a + 3) = 8
Value of a = 5
And, (b – 2) = 15
Value of b = 17
So, area of square = 3 x (17 – 5) = 36 cm^2
Value of c = (36)^(1/2) = 6 cm
So, length of rectangular sheet = (3 x 6 + d) =
(18 + d) cm
Breadth of rectangular sheet = (d + 4) cm
Volume of rectangular box = 432 cm^3
So,
(18 + d – 12) x (d + 4 – 12) x 6 = 432
(d + 6) x (d – 8) = 72
d^2 – 2d – 120 = 0
d^2 – 12d + 10d – 120 = 0
(d – 12) (d + 10) = 0
So, possible value of d = 12
So, length of rectangular box = (18 + 12) = 30
cm
Breadth of rectangle = (12 + 4) = 16 cm

According to question,
Area of cylinder to be painted = 2 x area of

Required cost = 4.5 x 2 x (30 x 16) = Rs. 4320 (B)
2.
Required value of c = 6 cm (A)
3.
Let the length of perpendicular drawn on
hypotenuse = K cm
Now,
1/2 x 15 x 8 = 1/2 x K x 17
Value of K = (15 x 8)/17
Required value = 17/4 x (15 x 8)/17 = 30 cm (C)

For Q
Let the cost price of article = 4b
Difference between cost price and marked price
= 40Z = 40 x 20 = Rs. 800
So, marked price of article = 4b + 800
Total discount offered = 800 x 75% = Rs. 600
Selling price of article = 5b x (1 – 1/15) = 14b/3
Now,
14b/3 + 600 = 4b + 800
2b/3 = 200
Value of b = 300
So, cost price of article = 300 x 4 = 1200
Marked price of article = 1200 + 800 = Rs. 2000
Selling price of article after first discount = 5 x
300 = 1500
So, (L – 5) = (2000 – 1500)/2000 x 100 = 25
Value of L = 25 + 5 = 30
For R
Total discount offered is Rs. 308 which is Rs. 8
more than that of article R.
Let cost price of article = c
So, marked price of article = 2 x c = 2c
Selling price after first discount = 175% x c =
7c/4
Total discount offered = Rs. 300
Ratio of marked price and selling price after first
discount = 2c:7c/4 = 8:7
So, value of Y% = (8 – 7)/8 x 100 = 12.5%
So, selling price after second discount = 7c/4 x
5/7 = 5c/4
Total discount offered = 2c – 5c/4 = 3c/4
So, 3c/4 = 300
Value of c = Rs. 400
For article S
Let cost price of article = Rs. d
Marked price of article = (d + 600)
Selling price after first discount = 1.52 x d =
1.52d
Selling price after second discount = 1.52d x
(100 – 12.5 x 1.2)/100 = 1.292d
Now,
(d + 600) – 1.292d = 308
0.292d = 292
So, value of d = 1000
So, marked price of article = 1000 + 600 = 1600
Selling price after first discount = 1.52 x 1000 =
1520
So, value of K = (1600 – 1520)/1600 x 100 = 5%
1.
According to question,
Value of Z = 20
Value of Y = 12.5
Required % change = (20 – 12.5)/12.5 x 100 = 60% (B)
2.
% Profit earned on article Q = (1400 –
1200)/1200 x 100 = (50/3) %
% Profit earned on article S = (1292 –
1000)/1000 x 100 = 29.2%
Required value = 15 x 29.2 x 50/3 x 1/100 = 73 (A)
3.
Article R
Selling price of article = Rs. 500
Discount % given = (10 x 5)/3 = 50/3%
So, new marked price of article = 500 x 6/5 =
Rs. 600
Mark up % = 7 x 12.5% = 87.5%
So, new cost price of article = 8/15 x 600 = Rs 320 (D)
4.
Value of C = 1600 – 1200 = 400
Value of D = 2000 – 800 = 1200
Required difference = 1200 – 400 = 800 (E)
5.
Cost price of (R + S) = 400 + 1000 = 1400
Cost price of (P + Q) = 800 + 1200 = 2000
Required % change = (2000 – 1400)/2000 x 100
= 30% (C)

Detailed Solution:
For P
Let the cost price of article = 100a
Article is marked up by 50%, so its marked price
= 100a x 150% = 150a
Selling price of article after first discount = 100a
x 120% = 120a
Now,
(100 – Z) = 120a/150a x 100
So, value of Z = 20
Total discount offered = Rs. 336
Now,
150a – 150a x 80% x 90% = 336
42a = 336
So, value of a = 336/42 = 8
So, cost price of article = 8 x 100 = Rs. 800
Marked price of article = 800 x 1.5 = Rs. 1200
Selling price of article = 1200 x 80% x 90% = Rs. 864
