- 36
- 64
- 56
Answers:
1) Answer: B
Originally, let the number of male and female in a committee be 5x and 6x respectively.
Their increased number is (112% of 5x) and (110% of 6x).
(112/100)*5 and (110/100)*6
=5.6 : 6.6
=56 : 66
=28 : 33
So, the required ratio = 28 : 33
2) Answer: B
4 times P’s share = 6 times Q’s share = 3 times R’s share
4*P = 6*Q
P/Q = 3/2
6*Q = 3*R
Q/R = ½
P : Q : R = 3 : 2 : 4
The sum of the total Salary,
3x+2x+4x=234
9x=234
X=234/9=26
Hence p gets =3x=3*26= Rs 78
3) Answer: B
Let the no. of 5p, 10p, 25 p coins be 3x, 3x & 5x respectively.
Then sum of their values = Rs. [(5*3x/100) + (10*3x /100) + (25*5x/100)]
=Rs. [(15x/100) + (30x /100) + (125x/100)]
=Rs. (15x+30x+125x / 100)
=Rs. (170x /100)
Therefore 170x / 100 = 34
X=34 *100/170
X=20
Hence the no. of 10p coins = 3x
=3*20
=60
4) Answer: D
Let the original salary of Naveena and Menaka be 6x and 5x respectively
Then, (6x+6000) / (5x+6000) = 38/35
35(6x+6000) = 38(5x +6000)
210x +210000 = 190x + 228000
210x – 190x = 228000 – 210000
20x = 18000
X=900
Menaka’s present salary = 5x
= 5*900 = Rs. 4500
5) Answer: D
Let the original salary of X & Y be 5x & 8x respectively
New salary of X = 40% of 5x
=140/100 * 5x
=700x /100
= 7x
New salary of Y = 85% of 8x
=185 /100 *8x
= 74x/5
Therefore 7x : 74x/5 = 10:9
7x*5/74x =10:9
We can’t find x, so the given data is inadequate
6) Answer: C
Let UG students be = 5x and
PG students be = 4x respectively
No. of those who do not get scholarship,
= 60% of 5x + 50% of 4x
= (60/100*5x) + (50/100*4x)
= 300x/100+ 200x /100
= 3x + 2x
= 5x
Required percentage = (5x/9x) *100
= 55.5%
7) Answer: B
Karan : Hari =5:3
Hari : Kowshik =5:3
Karan : Hari : Kowshik = 25:15:9
Therefore, the runs made by Karan,
=25/49*588
=25*12=300 runs
8) Answer: A
8A= 50B=> A/B=50/8
A : B= 50:8=>25:4
19C = 456
=>C=24
B=2*2C=4*24=96
4’S=96=>1’S=24
A=24*25=600
3A +4B=3*600+4*96=2184
9) Answer: B
Let the first and the third parts be 3x and 5x.
Second part = 1/4 of third part = (1/4) × 5x == 5x/4
Therefore, 3x + (5x/4) + 5x = 370
(12x + 5x + 20x)/4 = 370
37x/4 = 370
x = (370 × 4)/37
x = 10 × 4
x = 40
Therefore,
First part = 3x =3 × 40=120
Second part = 5x/4 =5 × 40/4=50
Third part = 5x =5 × 40=200
10) Answer: A
Two numbers are in the ratio of,
(1 ½): (2 2/3) =>3/2: 8/3 =>9:16 (9x, 16x)
1 2/3: 1 ½ =>5/3:5/2 =>2:3
9x+15/16x+15 =2/3
27x+45 = 32x+30
5x= 15
X=3
The larger of the numbers is, 16x= 48
