Dear Students,

**SSC**has released the notification for CGL. This time again the competition is going to be very stiff. Questions from Quant are asked in Tier-1 and Tier-II as well. Hence, you need to focus on this subject more. The only trick to master Quant is “**practice**‘. So, Practice daily. We are providing topic-wise quant quizzes, solve, learn, succeed.**Q1. Mr Amar spends 50% of his monthly income on household items and out of the remaining he spends 25% on travelling, 30% on entertainment, 15% on shopping and 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

S1. Ans.(a)

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?**

(a) 60

(b) 80

(c) 95

(d) 40

S2. Ans.(c)

Sol. Total marks of test = 80

Ankita scored = 65% of 40 Question (1 mark)

= 26

But she needs to score = 80% of entire ‘test’

= 80% of 80

= 64 marks

So, she needs = (64 – 26) marks

= 38

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?**

(a) 845

(b) 897

(c) 810

(d) 104

S3. Ans.(c)

Sol. No. of students = 60

No. of teachers = 5

No. of sweets each students got = 20% of (60)

= 12

Total sweets distributed among students

= 12 × 60 =720

No. of sweets each teacher got = 30% of (60)

= 18

Total sweets = 18 × 5 = 90

distributed among teachers

Total sweets = (720 + 90)

= 810

**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?**

(a) 7106

(b) 6840

(c) 8360

(d) 5814

S4. Ans.(d)

Sol. Let total votes = 100%

Invalid = 15%

Valid votes = 85%

1

^{st}candidate = 55% of 85%So, 2

^{nd}candidate = 45% of 85%According to the question,

100% → 15200

85% → 12920

Other candidate got = 45% of 12920

= 5814 vote

**Q5. On a test consisting of 250 questions, John answered 40% of the first 125 questions correctly. What percent of the other 125 questions does she need to answer correctly for her grade on the entire exam to be 60%?**

(a) 15.6

(b) 3.9

(c) 37.2

(d) 24

We’ll check the difference of two numbers

42 – 24 = 18 û

and

93 – 39 = 54 ü

So, number = 39

10% of 39 = 3.9
