Answers:
1) Answer: b)
Let us take one part be x and another one be 72000 – x,
According to the question,
x*[(1 + 10/200)2 – 1)] + [(72000 – x)*15*1]/100 = 9375
x*[(210/200)2 – 1)] + 10800 – (15x/100) = 9375
(41x/400) + 10800 – (15x/100) = 9375
(41x/400) – (15x/100) = 9375 – 10800
-19x/400 = -1425
x = 1425*(400/19) = 30000
The amount invested in S.I = 72000 – x = 72000 – 30000 = Rs. 42000
2) Answer: d)
Efficiency ratio of A and B = 4 : 5
Day ratio = > A : B = 5 : 4
A can fill the 3/5 of the tank in 15 min
= > (3/5)*work = 15 min
= > Whole work = 25 min
A takes 25 min to fill the tank, So, B takes,
= > 5’s = 25
= > 1’s = 5
B can fill the tank in, 20 min
B can fill the tank independently for 10 min only.
B’s 10 min work = 10/20 = 1/2
Remaining = 1 – 1/2 = ½
Half of the tank will remain incomplete.
3) Answer: c)
The ratio of present age of Kavin and her son’s age = 4 : 1 (4x, x)
Kavin’s present age = (2/5)* Kavin’s father’s present age
Kavin’s father’s present age = 10x
According to the question,
x + 4x + 10x = 120
15x = 120
x = 120/15
x = 8
Kavin’s father’s present age = 10x = 80 years
4) Answer: a)
Let the number of passed students be x,
45*12 = 14x + (45 – x)*5
540 = 14x + 225 – 5x
540 – 225 = 9x
9x = 315
X = 35
Total number of passed students = 35
= > 7 : 2
9’s = 45
1’s = 5
Total number of passed students = 7’s = 35
Shortcut:
= > 7 : 2
9’s = 45
1’s = 5
Total number of passed students = 7’s = 35
5) Answer: c)
For managing the business, Aravind receives,
= > 72000*(10/100) = Rs. 7200
Remaining = 72000 – 7200 = Rs. 64800
The ratio of investment of Aravind, Ganesh and Thyagu
= > 24000 : 30000 : 36000
= > 4 : 5 : 6
15’s = 64800
1’s = 4320
The share of Aravind = (4*4320) + 7200 = Rs. 24480
The share of Thyagu = (6*4320) = Rs. 25920
Required difference = 25920 – 24480 = Rs. 1440
Directions (6-10):
6) Answer: c)
For managing the business, Aravind receives,
= > 72000*(10/100) = Rs. 7200
Remaining = 72000 – 7200 = Rs. 64800
The ratio of investment of Aravind, Ganesh and Thyagu
= > 24000 : 30000 : 36000
= > 4 : 5 : 6
15’s = 64800
1’s = 4320
The share of Aravind = (4*4320) + 7200 = Rs. 24480
The share of Thyagu = (6*4320) = Rs. 25920
Required difference = 25920 – 24480 = Rs. 1440
7) Answer: d)
Total distance covered by P = 5600*(15/100) = 840 Km
P travels 60 km per day. After 2 days he reached (60*2) = 120 km.
Remaining distance = 840 – 120 = 720 Km
Required time = 2 + (720/180) = 2 + 4 = 6 hours
8) Answer: a)
Total distance travelled by U = 5600*(14/100) = 784 Km
Time = (784/56) = 14 hours
Total hours taken by him to collect the document = 2 + 2 = 4 hours
Remaining time = 14 – 4 = 10 hours
Required answer = (784/10) = 78.4 km/hr
Increased speed = 78.4 – 56 = 22.4 Km/hr
8) Answer: c)
Total distance covered by S = 5600*(24/100) = 1344 Km
The distance covered by him in 2 hours = 56 + 64 = 120 Km
Remaining distance = 1344 – 120 = 1224 Km
Required speed = (1224/17) = 72 Km/hr
9) Answer: b)
The total distance covered by P and R together
= > 5600*(33/100) = 1848 Km
The total distance covered by T and U together
= > 5600*(31/100) = 1736 Km
Required difference = 1848 – 1736 = 112 Km
10) Answer: d)
Total distance covered by Q = 5600*(12/100) = 672 Km
Let the speed of the car be x,
According to the question,
(240/160) + (156/78) + (276/x) = 15/2
(3/2) + 2 + (276/x) = (15/2)
(276/x) = (15/2) – (7/2)
(276/x) = 4
X = (276/4) = 69 Km/hr
Speed of the car = 69 Km/hr
