The correct answers to the above question in:
Answer: (a)
The raised price = $120/100$ of the former price
The householder must now consume $100/120$ of the original amount
The reduction in consumption = $(1 – 100/120)$ of the original consumption = $1/6$ of the original consumption
i.e. 1 : 6
Using Rule 8,
If the income of a man is A% more than another man, then income of another man is less in comparison to the 1st man by
$(A/(100 + A)× 100)%$
Required percentage = $(20/{100 + 20})×100$
= $20/120×100$ = $100/6$%

Question : 1
The ratio of the number of boys to that of girls in a village is 3 : 2. If 30% of boys and 70% of girls appeared in an examination, the ratio of the number of villagers, appreared in the examination to that not appeared in the same examination is
a) 1 : 1
b) 27 : 23
c) 23 : 27
d) 9 : 14
Answer »Answer: (c)
Boys in the village = 3x
Girls in the village = 2x
Villagers who appeared in the examination
= ${3x × 30}/100 + {2x × 70}/100$
= ${9x}/10 + {14x}/10 = {23x}/10$
Villagers who did not appear in the examination
= ${3x × 70}/100 + {2x × 30}/100$
= ${21x}/10 + {6x}/10 = {27x}/10$
Required ratio = ${23x}/10 : {27x}/10$ = 23 : 27
Question : 2
Two numbers are in the ratio 2 : 3. If 20% of the smaller number added to 20 is equal to the sum of 10% of the larger number and 25, then the smaller number is
a) 180
b) 200
c) 160
d) 100
Answer »Answer: (d)
Let the numbers be 2x and 3x.
According to the question,$(20/100 × 2x) + 20$
= $(10/100 × 3x) + 25$
${2x}/5 + 20 = {3x}/10 + 25$
${2x}/5 - {3x}/10$ = 25 - 20
${4x - 3x}/10$ = 5 ⇒ x = 50
The smaller number = 2x = 100
Question : 3
If 30% of A = 0.25 of B = $1/5$ of C, then A : B : C is equal to :
a) 6 : 5 : 4
b) 10 : 12 : 15
c) 5 : 24 : 5
d) 5 : 6 : 4
Answer »Answer: (b)
30% of A = 25% of B
30 A = 25 B
A : B = 25 : 30 = 5 : 6
Again, 25% of B = 20% of C
25 B = 20C ⇒ 5B = 4C
B : C = 4 : 5
A : B : C = 5 × 4 : 4 × 6 : 6 × 5
= 20 : 24 : 30 = 10 : 12 : 15
Question : 4
The difference of two numbers is 45% of their sum. The ratio of the larger number to the smaller number is
a) 29 : 11
b) 11 : 29
c) 9 : 20
d) 20 : 9
Answer »Answer: (a)
Let the numbers be x and y and x is greater than y.
Then x – y = 45% of (x + y)
x – y = $45/100(x + y)$
x – y = $9/20(x + y)$
20x – 20y = 9x + 9y
20x – 9x = 20y + 9y
11x = 29y
$x/y = 29/11$ or 29 : 11
Question : 5
The ratio of the number of boys and girls in a school is 3:2. If 20% of the boys and 25% of the girls are scholarship holders, the percentage of the school students who are not scholarship holders is
a) 70
b) 80
c) 78
d) 56
Answer »Answer: (c)
Let the number of students in school be 100.
Boys ⇒ 60 Girls ⇒ 40
Students who do not hold scholarship :
Boys ⇒ ${60 × 80}/100$ = 48 Girls ⇒ ${40 × 75}/100$ = 30
Required answer = 48 + 30 = 78 i.e., 78%
Question : 6
The bus fare and train fare of a place from Kolkata were Rs.20 and Rs.30 respectively. Train fare has been increased by 20% and the bus fare has been increased by 10%. The ratio of new train fare to new bus fare is
a) 5 : 3
b) 3 : 5
c) 18 : 11
d) 11 : 18
Answer »Answer: (c)
Increased train fare = Rs.$(120/100 × 30)$= Rs.36
Increased bus fare = Rs.$(110/100 × 20)$ = Rs.22
Required ratio = 36 : 22 = 18 : 11
