A) 4820
B) 5025
C) 5120
D) 5335
E) None

Option B
Solution:
Given
25% of four-fifth of 30% of a number is 301.5
Let the number be x.
25/100 * 4/5 * 30/100*x=301.5
X=5025.

Question 2: In a Bookshelf 60% of the books are in Tamil, 60% of the remaining books are in English rest of the books are in Hindi. If there are 2400 books in English, then the total number of books in Hindi are?
A) 1300
B) 1250
C) 1600
D) 1450
E) None

Option C
Solution:
Let there are X books in the Bookshelf.
Number of Tamil books = 60% of X = 60X /100 = 0.6X
Remaining Books = X – 0.6X = 0.4X
Number English books = 40% of reaming books = 60% of 0.4X = 0.24X.
Hindi Books = X-0.6X -0.24X = 0.16X
Given,
0.24X = 2400
X = 2400/0.24 = 10000
Urdu Books = 0.16X = 0.16*10000 = 1600.

Question 3: In a bank 70 percent employees are men. 80%men and 20%women belong to retirement plan.what percent of people belong to retirement plan?

D) 2800
E) None

Option C

Let the number of individuals involved in election be x.
Percentage of those who were not vote = 100-(40+45) = 15%
The difference between those who voted
45% of x – 15% of x = 630
30% of x = 630
x=630*100/30
=2100.

Question 5: he price of rice increases by 32%. A family reduces its consumption so that the expenditure of the rice is up by 10% only. If the total consumption of rice before the price was 10 kg per month, then the consumption of rice per month.
A) 7 1/2
B) 8 1/3
C) 8
D) 6
E) None

Option B
Solution:
Let initial price of sugar = Rs.100 per kg
initial consumption = 10 kg per month
Total expenditure on sugar = 100×10 = Rs.1000 per month
New price of sugar = Rs.132 per kg
Total expenditure = Rs.1100 per month ( 10% increase from Rs.1000)
Now, 1100/132 =25/3
=8 1/3kg.

Question 6: Weight of A and B are in the ratio of 3:5. If the weight of A is increased by 20 percent and then the total weight becomes 132 kg with an increase of 10 percent. B weight is increased by what percent.
A) 7%
B) 8%
C) 9%
D) 4%
E) None

Option D
Solution:
Weight of A and B are 3x and 5x.
Initial weight before increase = (132*100)/110 = 120
8x = 120. X = 15
Initial weight of A and B are 45 and 75 kg respectively.
New weight of A = 54 so weight of B = 132 – 54 = 78.
So % increase = [(78-75)/75]*100 = 4 % .

Q.7.Half of 1 percent written as decimal is :

(A) 0.005 (B) 0.05 (C) 0.02 (D) 2

1 2 % = ( 1 2 × 1 100 ) = 0.5 100 = 0.005 .

Question 8 : If 15% of 40 is greater than 25% of a number by 2, then the number is :

(A) 12 (B) 16 (C) 24 (D) 32

15 % o f 40 − 25 % o f x = 2 ⟺ 25 100 x = ( 15 100 × 40 ) − 2

Question 9 :What is the value of X in 130% of X = 40% of 845 ?

a) 123 b) 239 c) 142 d) none of these

Answer : d) none of these

Solution :

Given equation is 130% of X = 40% of 845

X x 130/100 = 40×845/100
130X = 40×845
X = 40×845/135 = 250.37

Hence the answer is option d.

Question 11 : The population of a town in 1991 was 175760. If it increases by 4% annually then what it was 1988?

a) 196520 b) 251100 c) 200950 d) 156250

d) 156250

Solution :

Population of the district in 1991 = 175760
We have to find the population in 1988. (3 years back).
Increasing rate = R = 4%

By using the formula (2),
Population = 175760/(1 + 4/100)³ = 175760 / (104/100)³
= 175760 x 25/26 x 25/26 x 25/26
= 10 x 25 x 25 x 25 = 156250

Hence the required answer is option d.
