40% of 20 = 2
Hence they are equal i.e. y of x% = x of y% is correct.

SSC CGL Percentage Previous Year Questions PDF
Q1. Mr. Amar spends 50% of his monthly income on household items and out of the remaining, he spends 25% on travel, 30% on entertainment, 15% on shopping, and the remaining amount of Rs. 900 is saved. What is Mr. Amar’s monthly income?
(a) Rs. 6,000
(b) Rs. 12,000
(c) Rs. 9,000
(d) Cannot be determined
Sol. House hold expenditure = 50%
Remaining = 50%
On Remaining amount he spends:-
Travelling = 25%
Entertainment = 30%
Shopping = 15%
Total = 70% ⇒ Remaining = (100 – 70) % of 50%
Rest amount ⇒ 900 = 30% of 50%
⇒ 15% = 900
100% = 6,000.
Q2. In a test consisting of 80 questions carrying one mark each, Ankita answers 65% of the first 40 questions correctly. What percent of the other 40 questions does she need to answer correctly to score 80% on the entire test?
S2. Ans. (c)
Sol. Total marks of test = 80
Ankita scored = 65% of 40 Question (1 mark)
But she needs to score = 80% of the entire ‘test’
= 80% of 80
= 64 marks
So, she needs = (64 – 26) marks
Percentage ⇒ x% of 40 = 38
⇒ x = 95
Q3. In a class of 60 students and 5 teachers, each student got sweets that are 20% of the total number of students and each teacher got sweets that are 30% of the total number of students. How many sweets were there?
S3. Ans. (c)
Sol. No. of students = 60
No. of teachers = 5
No. of sweets each student got = 20% of (60)
Total sweets distributed among students
= 12 × 60 =720
No. of sweets each teacher got = 30% of (60)
Total sweets = 18 × 5 = 90
distributed among teachers
Total sweets = (720 + 90)
Q4. In a college election fought between two candidates, one candidate got 55% of the total valid votes. 15% of the votes were invalid. If the total votes were 15,200, what is the number of valid votes the other candidate got?
Sol. Let total votes = 100%
Invalid = 15%
Valid votes = 85%
1st candidate = 55% of 85%
So, 2nd candidate = 45% of 85%
According to the question,
100% → 15200
85% → 12920
Other candidate got = 45% of 12920
= 5814 vote

We’ll check the difference between the two numbers
42 – 24 = 18 û
93 – 39 = 54 ü
So, number = 39
10% of 39 = 3.9
