b) 56.5 kg

c) 54.5 kg

d) 55.5 kg

e) None of the above

Required ratio = (40-34)/(34-30)=6/4=3/2

Let the numbers be a,b,c,d and e.

Now $\frac{a+b+c+d+e}{5}$=57.8*5

a+b+c+d+e=292

Now, $\frac{a+b}{2}$=77.5, a+b=155

Also, $\frac{d+e}{2}$=46, d+e=92.

Now, c=292-(a+b)-(d+e)=292-92-155=42.

Hence, the correct option is C.

Let the numbers be a,b,c,d,e.

Hence (a+b+c+d+e)/5=49

(a+b)/2=48, a+b=96.

(d+e)/2=28,d+e=56

c=245-96-56=93

The average score of a cricketer for 13 matches is = 42 runs

Total score in 13 matches will be = 42*13 = 546

Total score of first 5 matches will be = 54*5 = 270

Hence, total score of last 8 matches = 546-270 = 276

So average of the last 8 matches will be = $\frac{276}{8} = 34.5$

The average weight of 21 boys is 64 Kgs.

The average weight of 21 boys and the teacher is 65 Kgs.

So, total weight of 21 boys is 21*64 = 1344

The weight of 21 boys and the teacher = 22*65 = 1430

Hence, the weight of the teacher is 1430 – 1344 = 86 Kgs

Since the ages of A, B, C, D are consecutive

Let the ages of A, B, C, D be n, n+1,n+2,n+3

$\frac{n+n+1+n+2+n+3}{4} = 49.5$

4n+6 = 49.5*4 = 198

4n = 192

n = 48

Ages of A, B, C, D = 48, 49, 50 ,51

Product of ages of B and D = 49*51 = (50-1)(50+1) =$50^2-1$ = 2500-1 = 2449.

Let the maximum aggregate marks be x
780/x – 728/x = 5/100
52/x = 1/20
x = 52*20 = 1040

The average weight of 15 girls is 54 kgs.
Therefore, total weight = 810
Now, after adding teachers weight the average increase to 56 kgs
Let teachers weight be x.
(810+x)/16 = 56
x= 86
The teachers weight is 86 kgs.

The correct option is option D.

Let A = x
B= x+1
C= x+2
D=x+3
Now, average = 56.5
(A+B+C+D)/4 = 56.5
4x +6 = 56.5*4
4x +6 = 226
4x = 220
x = 55
Therefore A,B,C and D are 55,56,57 and 58 respectively.
Product of A and C = 55*57 = 3135

Average of all 20 matches = {Total runs scored in the first 18 matches + Runs scored in 19th match + Runs scored in 20th matches}$\div${20}
= ${(18*56.5 + 101 + 123)}\div{20}$
= 62.05

Let the average of the six batsmen be x.

So, runs scored by the captain = x+30

Total score of the team = 6x + x + 30 = 7x + 30 = 310 => x = 40

So, the score of the captain = 70

The average weight of the three boys P,T and R is $54 \frac{1}{3}$
So, the total weight of the three boys P,T and R is $3*\frac{163}{3} = 163$
So, P+T+R = 163

Similarly total weight of T,F and G is 53 kg.
So, the total weight of the three boys T,F and G is $53*3 = 159$
So, T+F+G = 159

Therefore, P+R+F+G+2T = 322

We need to find P+T+R+F+G in order to find the average weight of the five boys. However, as we don’t know the weight of T, we can’t find the average weight of the five boys.

The number of boys in the class is $\frac{5}{5+4}*45 = 25$
The number of girls in the class is $\frac{4}{5+4}*45=20$

Average marks obtained by boys is 76 and that of girls is 78.
Hence, the total marks obtained by the students is 76*25+78*20 = 3460

Therefore, the average marks obtained by the students together is 3460/45 = 76.89

Let the five odd numbers be a, a+2, a+4, a+6 and a+8.
Hence, their sum equals 5a + 20 and their average is a+4

As given in the question, (a+4)/(a+8) = 84/100 = 21/25
Therefore, 25a + 100 = 21a + 168
Or, 4a = 68
Hence, a = 17

Hence, the first two numbers are 17 and 19 and their sum is 36
