A box contains, 5 Sony, 6 Samsung and 4 SanDisk pen drives. 3 pen drives are drawn at random. What is the probability that they are different company?
Correct
Answer a
Total probability n(S) = 15C_{3}
Required probability n(E) = 5C_{1} and 6C_{1} and 4C_{1}

Question 13 of 20
13. Question
2 years ago, the ratio of Gowri and Nandhini’s age was 4:5. 8 years hence, this ratio would become 5:6. How old is Nandhini?
Correct
Answer c
2 years ago, the ratio of Gowri and Nandhini’s age = 4: 5(4x, 5x)
8 years hence, the ratio of Gowri and Nandhini’s age = 5: 6
According to the question,
= > (4x + 10) / (5x+10) = (5/6)
= > 24x + 60 = 25x + 50
= > x = 10
Nandhini’s present age = 5x + 2 = 52 years
Incorrect
Answer c
2 years ago, the ratio of Gowri and Nandhini’s age = 4: 5(4x, 5x)
8 years hence, the ratio of Gowri and Nandhini’s age = 5: 6
According to the question,
= > (4x + 10) / (5x+10) = (5/6)
= > 24x + 60 = 25x + 50
= > x = 10
Nandhini’s present age = 5x + 2 = 52 years
Question 14 of 20
14. Question
4 years ago, Sanjay got a gold medal for his studies. His present age is 3/2 times his age at the time of he got the prize. Sanjay’s brother was 5 years younger to him at the time of his prize event. The age of Sanjay’s brother is?
Correct
Answer b
4 years ago, Sanjay got a gold medal for his studies
The present age of Sanjay = (3/2)*at the time he got a gold medal
The ratio will be = 3: 2
He got gold medal 4 years ago, so,
(3’s – 2’s) = 4
1’s = 4
The present age of Sanjay = 12 years
Sanjay’s brother = Sanjay – 5
= > 12 – 5 = 7 years
Incorrect
Answer b
4 years ago, Sanjay got a gold medal for his studies
The present age of Sanjay = (3/2)*at the time he got a gold medal
The ratio will be = 3: 2
He got gold medal 4 years ago, so,
(3’s – 2’s) = 4
1’s = 4
The present age of Sanjay = 12 years
Sanjay’s brother = Sanjay – 5
= > 12 – 5 = 7 years
Question 15 of 20
15. Question
Train A of length 180 m crosses another train B travelling in opposite direction in 15 seconds. Train A crosses a pole in 20 sec and the length of train A is half of the length of train B then find the speed of train B in?
Correct
Answer a
Let the speed of train B be x,
Length of Train A = 180 m
Length of Train B = 360 m
T = D/S
{(180 + 360) / [(180/20) + x]} = 15
540/(9 + x) = 15
36 = 9 + x
X = 36 – 9 = 27 m/sec
Incorrect
Answer a
Let the speed of train B be x,
Length of Train A = 180 m
Length of Train B = 360 m
T = D/S
{(180 + 360) / [(180/20) + x]} = 15
540/(9 + x) = 15
36 = 9 + x
X = 36 – 9 = 27 m/sec

Directions (Q. 1 – 5):
Answer c
6^{3} × 3^{4} ÷ 9^{3} × x^{2} = 216
216 × (3^{4}/3^{6}) × x^{2} = 216
X^{2} = 3^{2}
X = 3
Answer a
(73/400)*17200 + (101/300)*1860 + (113/300)*19680= x
X = 3139 + 626.2 + 7412.8
X = 11178
Answer d
(30/100)*7560 – (27/100)*7800 + (56/100)*6250 = x
X = 2268 – 2106 + 3500
X = 3662
Answer b
(56/14)*180 + 175 + 56^{2} = x
X = 720 + 175 + 3136
X = 4031
Answer c
(21/5)*750 + 650 + (17/2)*1150 = x
X = 3150 + 650 + 9775
X = 13575

The answer is, 1460
Answer d
The pattern is, *2 + 7, *3 – 6, *4 – 5, *5 – 4, *6 – 3,..
The answer is, 1761
Answer d
N = 8 4/12 = 8 1/3 = (25/3) year
Total amount = 2P
Interest = 2P – P = P
P = PNR/100
P = P*(25/3)*R/100
R = 100*3/25 = 12 %
Answer a
Total probability n(S) = 15C_{3}
Required probability n(E) = 5C_{1} and 6C_{1} and 4C_{1}
P(E) = n(E)/n(S)
P(E) = 5C_{1} and 6C_{1} and 4C_{1} / 15C_{3}
P(E) = 24/91
Answer c
2 years ago, the ratio of Gowri and Nandhini’s age = 4: 5(4x, 5x)
8 years hence, the ratio of Gowri and Nandhini’s age = 5: 6
According to the question,
= > (4x + 10) / (5x+10) = (5/6)
= > 24x + 60 = 25x + 50
= > x = 10
Nandhini’s present age = 5x + 2 = 52 years
Answer b
4 years ago, Sanjay got a gold medal for his studies
The present age of Sanjay = (3/2)*at the time he got a gold medal
The ratio will be = 3: 2
He got gold medal 4 years ago, so,
(3’s – 2’s) = 4
1’s = 4
The present age of Sanjay = 12 years
Sanjay’s brother = Sanjay – 5
= > 12 – 5 = 7 years
Answer a
Let the speed of train B be x,
Length of Train A = 180 m
Length of Train B = 360 m
T = D/S
{(180 + 360) / [(180/20) + x]} = 15
540/(9 + x) = 15
36 = 9 + x
X = 36 – 9 = 27 m/sec
Directions (Q. 16 – 20) None of these
Answer a
The total number of students studied in the year 2013
= > 1574 + 2782 + 2570 + 1987 + 2117
= > 11030
The total number of students studied in the year 2015
= > 1736 + 1552 + 1474 + 1895 + 1915
= > 8572
Required ratio = 11030: 8572 = 5515: 4286
Answer c
The total number of students studied in the college R
= > 3128 + 2570 + 2454 + 1474 + 2890 + 1516
= > 14032
The total number of students studied in the college T
= > 1875 + 2117 + 2255 + 1915 + 2115 + 1799
= > 12076
Required difference = 14032 – 12076 = 1956
Answer d
Total number of students studied in College P and Q together in the year 2012 and 2014
= > 2548 + 1256 + 3045 + 1946 = 8795
Total number of students studied in College R and S together in the year 2016 and 2017
= > 2890 + 1912 + 1516 + 1894 = 8212
Required % = (8795/8212)*100 = 107.099 % = 107 %
