Answers & Solutions:<\/strong><\/span><\/p>\n

1)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

Require sum of 1+3+5+7+9….99
\nApplying formula for summation of n digits with a as first digit and d is the difference
\nsum =\u00a0$\\frac{n}{2} (2a + (n-1) d)$
\nor this formula can be reduced to\u00a0$\\frac{n}{2}\u00a0\\frac{a + l}{2} $hence for calculating avg. it will be
\n$\\frac{a + l}{2}$ (where $l$ is last term)
\nso\u00a0$\\frac{1\u00a0+ 99}{2}$ = 50<\/p>\n

2)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Let’s say numbers are $a, a+2, a+4$
\nSo avg. will be $\\frac{(a+a+2+a+4)}{3} = \\frac{a}{3} +12$
\nOr a = 15
\nSo numbers will be 15, 17, 19<\/p>\n

3)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

As we know average of numbers which are in A.P. is = $\\frac{a+l}{2}$ (where a is first term and l is last term)
\nHere a=3
\nand l= 27
\nHence average will be 15<\/p>\n

4)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

let his average of 10 matches = x<\/p>\n

total runs in 10 matches = 10x<\/p>\n

in 11th match he scored 100 runs, so<\/p>\n

total runs after 11th match = 10x + 100<\/p>\n

average of 11 matches = (10x+100)\/11<\/p>\n

after 11th match\u00a0the average of his runs is increased by 5, so<\/p>\n

(10x+100)\/11 = x+5<\/p>\n

10x+100 = 11x + 55<\/p>\n

x = 45<\/p>\n

but present average = x+5 = 45+5 = 50<\/p>\n

so the answer is option C.<\/p>\n

5)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

Let the 6 consecutive numbers be a-3,a-2,a-1,a,a+1,a+2<\/p>\n

average = $\\frac{SumofElements}{NumberofElements}$<\/p>\n

It is given that average of 6 consecutive numbers be k and hence<\/p>\n

k = $\\frac{a-3+a-2+a-1+a+a+1+a+2}{6}$ = $\\frac{6a-3}{6}$ = a – $\\frac{1}{2}$<\/p>\n

now next two numbers (a+3, a+4) are also added<\/p>\n

Sum of 8 numbers = a-3+a-2+a-1+a+a+1+a+2+a+3+a+4 = 8a +4 <\/span><\/p>\n

average of 8 numbers = $\\frac{8a+4}{8}$ = a + $\\frac{1}{2}$ = k + 1<\/span><\/span><\/span><\/p>\n

so average of 8 numbers is more than average of 6 numbers by = k+1 – K = 1<\/span><\/span><\/span><\/p>\n

6)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

we know that average =$\\frac {sum of elements}{numberof elements} $<\/p>\n

Number of elements =7<\/p>\n

Sum of elements = 7+11+15+14+21+25+x = 93+x<\/p>\n

=> Average = $\\frac {93+x}{7} $<\/p>\n

=> 15 = $\\frac {93+x}{7} $<\/p>\n

=> x = 12<\/p>\n

7)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

Let the total number of members in the institution be z<\/p>\n

average = $\\frac{SumofElements}{NumberofElements}$<\/p>\n

Average salary of institution = Rs 60<\/p>\n

total salary of Institution =Rs 60z<\/p>\n

Given that out of z persons , there are 12 officers and there average salary is = Rs 400<\/p>\n

and so total salary of 12 officers = 12 x 400 =Rs 4800<\/p>\n

So total salary of other (z-12) members =Rs ( 60z – 4800 )…………..(1)<\/p>\n

It is given that average salary of (z-12) persons = Rs 56<\/p>\n

and hence from here the total salary of (z-12) people = Rs 56(z-12)……….(2)<\/p>\n

Equation 1 and 2 are equal<\/p>\n

60z – 4800 = 56z – 672<\/p>\n

4z = 4128<\/p>\n

z = 1032<\/p>\n

8)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

Average = $\\frac{Sum of Elements}{Number of Elements}$<\/p>\n

Given that Initially Number of Elements = 50<\/p>\n

Initial Average = 38<\/p>\n

Sum of Elements = 50 x 38 = 1900<\/p>\n

Now as two numbers are discarded, hence number of elements left = 48<\/p>\n

Sum of elements after discarding numbers = 1900 – 55 – 45 = 1800<\/p>\n

Hence New Average = $\\frac{1800}{48}$ = 37.5<\/p>\n

9)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

avg age of a,b,c = 84<\/p>\n

$\\frac{A+B+C}{3}$ = 84<\/p>\n

A+B+C = 84*3 =252 ……………………(1)<\/p>\n

similarly , $\\frac{A+B+C+D}{4}$ = 80<\/p>\n

A+B+C+D = 80*4 = 320<\/p>\n

so using (1)<\/p>\n

252 + D = 320<\/p>\n

D = 68 i.e, E = 72 (as mentioned in the question)…………….(2)<\/p>\n

$\\frac{B+C+D+E}{4}$ = 78<\/p>\n

B+C+D+E = 78*4 = 312<\/p>\n

using (2)<\/p>\n

B+C+68+72 =312<\/p>\n

B+C = 172 ……………………………(3)<\/p>\n

put (3) in (1)<\/p>\n

A = 80<\/p>\n

10)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

Given that average of 20 numbers = 15<\/p>\n

using average = $\\frac{Sum}{Numberof Elements}$<\/p>\n

Sum of all numbers = 20 x 15 = 300<\/p>\n

Average of first five numbers = 12<\/p>\n

So sum of first five numbers = 12×5 = 60<\/p>\n

Sum of numbers left = 300 – 60 = 240<\/p>\n

Number of numbers left = 20 – 5 = 15<\/p>\n

So average of left numbers = $\\frac{240}{15}$ = 16<\/p>\n

11)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

let the present age of Ram , Ram’s wife ,and his two children be R ,W,S1,S2 respectively<\/p>\n

Average =$\\frac{SumofAges}{Number of Ages}$<\/p>\n

Given that average age of Ram and his childrens is =17 years<\/p>\n

R+S1+S2= 17 \u00d7 3 = 51<\/p>\n

Given R = 33 years .So, S2+S2 = 51-33 = 18 years<\/p>\n

Now given that average age of Rams wife and two children = 16 years<\/p>\n

So ,<\/p>\n

W+S2+S1= 16\u00d73=48<\/p>\n

W= 48-18 =30 years<\/p>\n

12)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

the average age of 14 girls and teacher is given as 15 and as we know<\/p>\n

Average = $\\frac {sum of ages}{number ofpersons}$<\/p>\n

Sum of ages of girls and teachers = 15\u00d715 =225 years<\/p>\n

Now the age of teacher is excluded and as a result the average reduced by 1 .So<\/p>\n

New average = 14<\/p>\n

New number of persons = 14<\/p>\n

Hence new sum of ages after exclusion of teacher = 14x 14 = 196<\/p>\n

Hence age of teacher =225-196 = 29 years<\/p>\n

13)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Given that average age of 50 members = 38 years<\/p>\n

So using , average = $\\frac{SumofAge}{number of persons}$<\/p>\n

Sum of ages = 50 x 38 = 1900<\/p>\n

Now 45 and 55 are discarded and hence number of term left = 48<\/p>\n

and Total Sum left = 1900 – 45 – 55 = 1800<\/p>\n

New Average = $\\frac{1800}{48}$ = 37.5<\/p>\n

14)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

average age of 5 members = 33×5 = 165 years<\/p>\n

given that youngest member has age = 9 years<\/p>\n

so 9 years ago , youngest member was not present and for other 4 people, 9 years will be reduced from each person’ age and hence<\/p>\n

total age of 4 members apart from the youngest one 9 years ago = 165- 9 – 36 = 120 years<\/p>\n

average age when the youngest member was born = $\\frac{120}{4}$<\/p>\n

= 30 years<\/p>\n

15)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

Given,A<\/span><\/p>\n

Average of 50 students in a class = 64<\/span><\/p>\n

Marks of two members were wrongly copied as 38 and 42 instead of 83 and 24.
\n<\/span><\/p>\n

Mean = $\\frac{\\text{Sum of all observations}}{\\text{Number of Observations}}$<\/p>\n

let the sum of all observations be x<\/p>\n

According to the problem,<\/p>\n

64 = $\\frac{x}{50}$<\/p>\n

$64\u00d750$ = $x$<\/p>\n

$x$ = 3200<\/p>\n

Subtract the wrongly copied numbers from the total sum<\/p>\n

= $3200 – (38+42)$<\/p>\n

= $3200 – 80$<\/p>\n

= $3120$<\/p>\n

Now add the new numbers to the total sum<\/p>\n

= $3120 + (83+24)$<\/p>\n

= 3227<\/p>\n

Thus, new sum is 3227<\/p>\n

New Mean = $\\frac{3227}{50}$ = 64.54<\/p>\n

Therefore, new Mean = 64.54<\/p>\n
