» Explain it
A
From Statement I:

Cost price of a shirt = 1100 Rs.

Selling price = 1100 + 55 = 1155 Rs.

Marked price = 1155 / 77 × 100 = 1500 Rs.

Statement I is sufficient to answer the question.

From Statement II:

Let the cost price = x Rs.

Marked price  = x × 136% = 1.36x

Selling price = x + 200

Statement II is not sufficient to answer the question.

Hence, option A is correct.

A
From Statement I:

Let Anuj = 4x, Vipin = 5x

Sanjeev = 4x + 4

From Statement II:

Anuj = 20 years, Sanjeev = x, Vipin = x + 1

Statement III:

Let age of Mohan = m years

Sanjeev = m - 5 years

From Statement I + Statement II:
Anuj = 20 years, Vipin =  20  × 5x = 25 years
4x

Sanjeev = 25 – 1 = 24 years

Statement I and II both are necessary to answer the question.

Hence, option A is correct.

E
From Statement I:

Time = 25 seconds

Relative speed =  length of trains
time

=   length of trains
25

From Statement II:

Length of train Y = 320m

Difference of speed = 14 km/h

From Statement III:

Let the speeds = 19x, 26x

Statement I + Statement II + Statement III

26x – 19x = 14

7x = 14

x = 2

Speed = 52 km/h, 38 km/h
 
(52 + 38) ×  5  =  (a + 320)
18 25

25 × 25 = a + 320

625 – 320 = a

a = 305 m

Therefore, all the statements are necessary to answer the question.

Hence, option E is correct.
 
» Explain it
A
From Statement I:

Let radius = r, height = h

Curved surface area = 2πrh

396 = 2 ×  22  × r × h
7

r × h = 63

Total Surface area = 2πrh + 2πr2
 
1628 =  22 (rh + r2)
7

rh + r= 259

63 + r= 259

r= 259 - 63 = 196

r = 14

r × h = 63

14 × h = 63

h = 4.5 cm

Statement I is alone sufficient to answer the question.

From Statement II:

r = 3h + 0.5 

Statement II is not alone sufficient to answer the question.

Hence, option A is correct.
 
» Explain it
C
From Statement I:

Let sum = x ?, rate = y%

x = x × 12.5 × y%

y = 8%

Statement I is alone sufficient to answer the question.

From Statement II:

A = P ( 1 +  r ) t
100  

5832 = 5000 ( 1 +  r ) 2
100  

5832  =  ( 1 +  r ) 2
5000 100  

729  =  ( 1 +  r ) 2
625 100  

27  =  1 +  r
25 100

27  – 1 =  r
25 100

2  =  r
25 100

r = 8%

Statement II is also alone sufficient to answer the question.

Hence, option C is correct.
