Questions and Answers

Q 1 - A understudy strolls from his home at 5/2 km/hr and achieves his school late by 6 min. Following day, he builds his pace by 1 km/hr and achieves a 6 min. before educational time. How far is the school from his home?

A - 5/4 km

B - 7/4 km

C - 9/4 km

D - 11/4 km

Answer : B

Explanation

Let the required distance be x km. then,
x/ (5/2) - x/ (7/2) = 12/60 (  ∵difference between two times is 12 min.)
⇒ 2x/5 - 2x/7 = 1/5   ⇒ 14 x-10 x = 7 ⇒ 4x= 7 ⇒ x= 7/4
Required distance = 7/4 km

Q 2 - A man loses Rs 55.50 yearly when the yearly rate of interest tumbles from 11.5% to 10%. His capital is:

A - Rs 3700

B - Rs 7400

C - Rs 8325

D - Rs 11100

Answer : A

Explanation

Let the capital be Rs. x. then,
(x*23/2*1/100*1) ?(x*10*1/100*1) = 55.50
=> 23x/200 ?x/10 =111/2 => 23x-20x =11100 => 3x= 11100 => x = 3700
Hence, the capital is Rs. 3700.

Q 3 - A person incurs 10% loss by selling a refrigerator for Rs 5400. At what price should the refrigerator be sold to earn 10% profit?

A - 5700

B - 6000

C - 6300

D - 6600

Answer : D

Explanation

SP=5400 X  (110)/90=6600.

Q 4 - 15% of 180 = 50% of?

A - 48

B - 50

C - 52

D - 54

Answer : D

Explanation

Let 15% of 180=50% of x
Then 15/100*180=50/100*x
=>x=54

Q 5 - A round greenery enclosure has an outline of 440 m. There is a 7m wide fringe inside the patio nursery along its outskirts. The territory of the fringe is:

A - 2918m2

B - 2921 m2

C - 2924 m2

D - 2926 m2

Answer : D

Explanation

2πR =440 ⇒ 2*22/7*R= 440 ⇒R= (440* 7/44)=70 m
Outer radius = 70m, inner radius = (70-7) =63 m
Required area = π [(70)2-(63)2] m2= 22/7 *(70+63) (70-63) m2
= (22*133) m2, = 2926m2

Q 6 - What was the week's day on seventeenth June, 1988?

A - Monday

B - Tuesday

C - Wednesday

D - Thursday

Answer : D

Explanation

17th June, 1998= (1997 year Period structure 1.1.1998 to 17.6.1998)
Odd days in 1600 year=0.
Odd days in 300 year = (5*3) =1.
97 year has 24 jump year +73 standard years.
= 24*2 + 73*1
= 48 + 73
= 121 odd days
= 17 weeks + 2 odd days = 2 odd days
= 2 odd days.
∴ 1998 years have (0+1+2) = 3 odd days

Jan to June = (31+29+31+30+31)
= 152 days

Add 17 days of June.
= 152 + 17
= 169 days
= 24 weeks + 1 days
= 1 odd day.

∴ Total number of odd day = 3 + 1 = 4 odd days.
Hence 17.06.1998 was Thursday.

Q 7 - A shopkeeper professes to sell all things at a discount of 20% ,but increases selling price of each article by 30% .His gain on each article is

A - 3%

B - 4%

C - 5%

D - 6%

Answer : B

Explanation

Let us assume cost price is 100.Then the marked price is 130
SP=130 * 80/100= 104.
Profit % =(S.P-C.P)/(C.P) * 100=(104-100)/100 * 100 
=4%

Q 8 - An aeroplane when 750 m high passes vertically above another aeroplane at an instant when their angles of elevation at same observing point are 45° and 30&de; respectively. Approximately, how many meters higher is the one than the other?

A - 250(1- √3)

B - 750(3- √3)

C - 250(3- √3)

D - 275(1- √3)

Answer : C

Explanation

Height & Distance Solution 5

Let C and D be the position of the aeroplanes.
Given that CB = 900 m,∠CAB = 60°,∠DAB = 45°
From the right △ ABC,
Tan45=CB/AB=>CB=AB
From the right △ ADB,
Tan30=DB/AB=>DB=ABtan30=CBx(1/√3)=750/√3
CB=CD+DB
=> Required height CD=CB-DB=750-750/√3=250(3- √3)

Q 9 - Two funnels can fill a tank in 20 minutes and 30 minutes separately. On the off chance that both the channels are opened at the same time, then the tank will be filled in:

A - 10 min

B - 12 min

C - 15 min

D - 25 min

Answer : B

Explanation

Part filled by both pipes in 1 min. =(1/20+ 1/30)= 5/60  = 1/12
Time taken to fill the tank = 12 minutes

Q 10 - The aggregate surface territory of a strong barrel is 231 cm2. On the off chance that its bended surface zone is two ?third of its aggregate surface zone, then its Volume is:

A - 269.5 cm3

B - 385 cm3

C - 308 cm3.

D - 363.4 cm3

Answer : A

Explanation

(2πrh+2πr2) =231 and 2πrh= 2/3*231= 154
∴154+ 2πr2 =231 ⇒2*22/7*r2= (231-154) =77
⇒r2 = (77*7/44)= 49/4 ⇒ r =7/2 cm
∴2*22/7*7/2*h= 154   ⇒ h= 7cm
∴ Volume = πr2h = (22/7 *7/2 * 7/2 * 7) cm3 = 539/2 =269.5 cm3
