Answers :
1) Answer: a)
The share of Ashok, Karthi and Mahesh
[5x*1 + (5x + 15000)*2] : [4x*3] : [7x*2 + (7x + 12000)*1] = 30 : 20 : 37= > [5x + 10x + 30000] : 12x : [14x + 7x + 12000] = 30 : 20 : 37
= > [15x + 30000] : 12x : [21x + 12000] = 30 : 20 : 37
According to the question,
= > 12x/(21x + 12000) = 20/37
= > 111x = 105x + 60000
= > 6x = 60000
= > x = 10000
Initial investment of Karthi = 4x = Rs. 40000
2) Answer: b)
C can empty the full tank in,
60 % of tank = 15
Full tank = 15*(100/60) = 25 hours
A, B and C’s one hour work = 1/15 + 1/20 – 1/25 = 23/300
(A, B and C)’s 8 hour work = (23/300)*8 = 46/75
Remaining work = 1 – 46/75 = 29/75
A and C’s one day work = 1/15 – 1/25 = (10-6)/(150) = 4/150
= 2/75
According to the question,
(29/75)*(75/2) = 29/2 = 14 ½ hours
The tank can be full in, 8 + 14 ½ = 22 ½ hours
3) Answer: b)Â Â Â Â Â Â Â Â Â Â Â Â Â
6 years ago, the ratio of the ages of Arun and Bharathi = 4 : 5 (4x, 5x)
Present ages of Arun and Bharathi = 4x + 6, 5x + 6
Present age of Ragu = (1/6)* Bharathi’s present age + 10
Arun’s present age = 36-6 = 30 years
According to the question,
4x + 6 = 30
4x = 24
x = 6
Bharathi’s present age = 5x + 6 = 36
Ragu’s present age = (1/6)*36 + 10 = 16
Required ratio = 36: 16 = 9: 4
4) Answer: c)
The area of the equilateral triangle = 196√3 Sq cm
The area of the equilateral triangle = (√3/4)*a2
(√3/4)*a2 = 49√3
a2 = 49*4
Side (a) = 7*2 = 14 cm
Radius (r) = 14 cm
Circumference of the circle = 2Ï€r = 2*(22/7)*14 = 88 cm
5) Answer: d)
Shortcut:
(100+ Profit %)/SP1 = (100 + Profit %)/SP2
(100 + 15)/690 = (100 + 25)/SP2
(115/690) = (125/SP2)
SP2 = 125*(690/115) = Rs. 750
Direction (6-10) :
6) Answer: a)
A can complete the work in 10 days
R can complete the same work in,
C : R = 1 : 2
1’s = 12
R can complete the same work in = 2’s = 24 days
(A + R)’s one day work = 1/10 + 1/24 = 34/(10*24) = 17/120
(A + R)’s 5 day work = (17/120)*5 = 17/24
Remaining work = 1 – (17/24) = 7/24
(7/24)*(R + M)’s whole work = 7/2
(R + M)’s whole work = (7/2)*(24/7) = 12 days
M’s one day work,
= > (1/12) – (1/24) = 1/24
M alone can complete the work in, 24 days
7) Answer: d)
B can complete the work in, 15 days
S can complete the same work in,
D: S = 6: 7
6’s = 18
1’s = 3
S can complete the same work in = 7’s = 21 days
(1/15 + 1/21)*x + (9/21) = 1
(1/15 + 1/21)*x = 1 – (9/21)
(1/15 + 1/21)*x = 1 – 3/7
[36/(15*21)]*x = 4/7X = (4/7)*(15*21)/36
X = 5 days
B left the job after 5 days of the work.
8) Answer: b)
B can complete the work in, 15 days
R can complete the same work in,
C : R = 1 : 2
1’s = 12
R can complete the same work in = 2’s = 24 days
1/15 + 1/24 + 1/N = 1/8
1/N = (1/8) – (1/15 + 1/24)
1/N = 1/8 – 13/120
1/N = 1/60
N can complete the work alone in 60 days.
The efficiency of B, R and N are in the ratio of,
= > (1/15) : (1/24) : (1/60)
= > 8 : 5 : 2
15’s = 7500
1’s = 500
The share of N = 2’s = Rs. 1000
9) Answer: a)
A’s one day work = 1/10
C’s one day work = 1/12
E’s one day work = 1/20
C+ E’s one day work = 1/12 + 1/20 = (5+3)/60 = 8/60
= 2/15
x/10 + (9/2)*(2/15) = 1
x/10 + 3/5 = 1
x/10 + 6/10 = 1
x+6 = 10
X = 4 days
10) Answer: c)
D can complete the work in 18 days.
M is 50 % more efficient than D
Efficiency ratio = > M: D = 150: 100 = 3: 2
Day ratio = > M: D = 2: 3
3’s = 18
1’s = 6
M can complete the work in = 2’s = 12 days
(1/12 + 1/18)*x = 1/3
[30/(12*18)]*x = 1/3X = 12/5 = 2 2/5 days
One-third of the work can be completed in 2 2/5 days
