Solution: (SP(A))/(CP(A)) = 120/100____________
(1) (SP(B))/(CP(B)) = 160/100____________
(2) (SP(B))/(sp(A)) = 250/100____________
Given (1)/ (2) =(CP(B))/(CP(A)) x100/250 
= 120/100 x 100/160 =(CP(B))/(CP(A)) 
= 15/8 = (CP(B)-CP(A))/(CP(A)) x100 
=(15-8)/8 x 100 =87.5%

Solution:
Let cost price of 1m cloth = CP
Profit = 8CP
& cost price of 32 m cloth = 32 CP
Profit percent = 8CP/32CP x 100
= 25%

Solution:
Equivalent percentage change = 20 + 25 +(20x25 )/100 = 50%
Population after 2 year = 1,02,000 + 50% of 1,02,000 = 1,53,000

Solution: We know,
Distance = Speed × Time
3hr 45 min = 15/4 hrs
Distance covered = 5*15/4
= 18.75 km = 19 (approx.)
New Speed =15 km/hr
Time taken = Distance /Speed
= 19/15
= 1.2 hrs

6.A captain of a small ship covers a distance 
of 2000 km in a time span of 60 days and takes 
rest for about 4 hours a day. If he sails the ship 
at a speed 5⁄2 times of the previous day and takes 
rest for 8 hrs, then how long will he take to cross 1250 km?

Solution: Prior speed of the ship = 2000/(60*(24-4))km/h
 = 5/3 k
New speed = 5/3 * 5/2 km/h = 25/6 km/h
Per day the ship sails for (24-8)= 16 hours
Each day the ship covers = 5*16 Kms = 80 kms
The total time taken for covering 1250 Kms = 1250/80
= 15.62 days

1.Arrange the following words in a meaningful sequence. 1. Interval 2. Assembly 3. Class lecture 4. Homework
A. 23154

2. In a certain code BEHAVE is written down as CEIANA. Then how SEVERE will be written on the basis of the same code language?
A. TEWESE
B. TESEWA
C.TEWSFG
D.NONE

Explanation: In the word BEHAVE, the even numbered letters remains the same and the odd numbered words that are B H and V changes. For these three letters the very next words are used that are, C, I, and V. For SEVERE the same code language will be used. E, E, and E on 2nd, 4th, and 6th place will remain same, S will become T, V will become W, and R will become S. hence the code for SEVERE is TEWESE.

3. In a certain code TRADITION is written down as ARTTIDNOI. Then how VERIFY will be written on the basis of the same code language?

A. IRYFEY
B.EVIRGF
C. EVIRYF
D. ETIRGF

Explanation: The letters are divided in 3 groups, TRA, DIT, and ION. Then they are reversed. So it becomes ART, TID, and NOI. Thus the word becomes ARTTIDNOI. Therefore, for the word VERIFY the same code language will be used. VE becomes EV, RI becomes IR, and FY becomes YF. So the code is EVIRYF.

4.In a certain code PROPER is written down as POREPR. Then how ISSUES will be written on the basis of the same code language?

A. ISSEUE

B. ISSEUS

C. ISSEUF

D. IRREUS

Explanation: In the word PROPER, the first and last word remains the same but
the places of 2nd and 3rd words are interchanged also the places of 4th and 5th
word is also interchanged. So the code becomes POREPR. Therefore for the word
ISSUES the same code will be applies, so, the code is ISSEUS.

5.In a certain code DARK is written down as ECVP. Then how HOUR will be written on vthe basis of the same code language?

A. JRYW
B. JRYW
C. JRYW
D.JRYW

Option(A)
Explanation
Each letter moves from +2, +3, +4, and +5
Therefore, DARK becomes ECVP
The same code language will be used for HOUR, +2, +3, +4, +5
Thus, it becomes JRYW.

1. She went to the hip-hop classes __________a month.
A. in
B.for
C.form
D.none
Explanations
‘For’ is used to denote a period, ‘from’ specifies the duration of the action from

2.My cat was playing ________ the table.
A.in
B.for
C.from
D.Under
Explanations:

3.Generally, there are heavy rains ____________ the month of July.

Solutions: - For months, ‘in’ is used, ‘on’ is used for special day and ‘at’ is used for a specific
period.

4.There was a cold breeze and snow ______ December.
A. in
B.at
C.for
D.none
Explanations
For months, ‘in’ is used, ‘on’ is used for special day and ‘at’ is used for
specifying a period.

Solutions:According to the style of the sentence, ‘outside’ will be used as it is specifying
the connection between the two clauses of the sentence.
