Answers & Solutions for\u00a0Average Questions for SSC CGL PDF:<\/strong><\/span><\/p>\n

1) Answer (A)<\/strong>
\nAs incomes of A and B are in the ratio 3 : 2. So , assume incomes of A and B be 3z and 2z
\nrespectively
\nAs the expenditure are in the ratio 5:3. So assume expenditure of A and B be 5y and 3y
\nrespectively
\nNow it is given that every one saves Rs 1000
\n3z – 5y = 1000 ……….(1)
\n2z – 3y = 1000……….(2)
\nSolving equations 1 and 2
\ny = Rs 1000
\nz = Rs 2000
\nhence income of A = 3z = 3 x 2000 = Rs 6000<\/p>\n

2) Answer (D)<\/strong>
\nlet the marked price of the article be Rs y
\nIst case :<\/strong>
\nTwo succesive discounts 40% followed by 30%
\nSo after these two successive discounts the value of article becomes = 0.6 \u00d7 0.7 \u00d7 y = 0.42 y
\n2nd case:<\/strong>
\nTwo successive discounts are 45% followed by 20%
\nSo after these two discounts the price if article becomes = 0.55 \u00d7 0.8 \u00d7 y = 0.44y
\nIt is given that :
\n0.44y – 0.42y = 12
\n0.02y = 12
\ny = Rs 600<\/p>\n

3) Answer (A)<\/strong>
\nChecking option 1 )
\n12: 9 = 4:3, 16 : 12 = 4:3
\nChecking option 2)
\n13 : 11 = 13:11 , 5 : 4= 5:4
\nchecking option 3)
\n30 : 45 = 2:3, 26 : 24 = 13:12
\nChecking option 4)
\n6 :10 = 3:5, 4: 10 = 2:5
\nSo option A is correct<\/p>\n

4) Answer (C)<\/strong>
\nlet the numbers of 5 candidates be a-3,a-1,a+1,a+3,a+5
\nIt is given that
\na-3+a-1+a+1+a+3+a+5 =185
\n5a + 5 = 185
\n5a = 180
\na= 36
\nThe highest score = a + 5 = 36 + 5 = 41<\/p>\n

5) Answer (A)<\/strong>
\nAs the numbers are in the ratio of 1:2:3 so let the numbers be y,2y,3y
\nThe numbers taken are co prime, => the highest common factor = y
\nand y = 12
\n=> Numbers are 12,24,36<\/p>\n

6) Answer (B)<\/strong>
\nAs the numbers are in the ratio 3:4
\nso assume the numbers are 3z and 4z
\nLCM of 3z and 4z = 12z
\nit is given that LCM of the above two numbers are = 180
\nSo, 12z = 180
\nz = 15
\nand hence 2nd number = 4z = 4 x 15 = 60<\/p>\n

7) Answer (A)<\/strong>
\nIt is given that A person distributes his pens among four friends A, B. C, D in the ratio 1\/3 : 1\/4 : 1\/5 : 1\/6
\nSo when he is distributing pens , then the number of pens distributed to everyone should be a natural number and hence the number of total pens should be a multiple of 3,4,5,6
\nand the smallest natural number divisible by 3,4,5,6 is its LCM which is = 60
\nand hence minimum 60 pens should be there with the man before distribution.<\/p>\n

8) Answer (B)<\/strong>
\nLet the total number of people be 100 and total marks be 100.
\nAverage = 52 => Total = 5200
\nAverage of brightest 20 = 80=>Total marks scored by brightest 20 = 80*20 = 1600
\nAverage of dullest 25 =31. => Total marks scored by dullest 25 = 25*31= 775
\nMarks scored by remaining 55 = 5200 -1600 – 775 = 2825
\nAverage = 2825\/55 = 51.4 % (Approx.)
\nOption B is the right answer.<\/p>\n

9) Answer (C)<\/strong>
\nNumber of teachers = 10 years
\nLet the initial average age be A years
\ntotal age before retirement = 10A
\nNow new average age =( A-3) years
\nSo new total age after new person joined= 10x(A-3) = 10A – 30 ………….(1)
\nlet the age of retired teacher be z years, So
\nnew total age can be calculated also as= 10A – z +25 ……..(2)
\nequations 1 and 2 are equal
\nso, 10A – 30 = 10A – z +25
\nz = 55 years.<\/p>\n

10) Answer (D)<\/strong>
\nInitial ratio of the numbers 1:2:3
\nSo, let the numbers be y , 2y , 3y
\nNow adding 5 to each number will give us y+5, 2y+5, 3y+5
\nas it is given that new ratio is 2:3:4 so assume that the new numbers are 2z, 3z, 4z
\nand hence we can relate numbers in following way:
\ny+5 = 2z…………(1)
\n2y + 5 = 3z……..(2)
\n3y+5 = 4z ………..(3)
\nfrom equation 1 and 2
\ny = 5 and z = 5
\nSo initially the numbers are
\n(5 , 10 , 15 )<\/p>\n
