Option 1: 75
Option 2:  82
Option 3:  80
Option 4:  84
Option 5:  85

Answer: 2:  82

Explanation:
I + II + III = 83 × 3 = 249  …… (i)
II + III + IV + V = 86 × 4 = 344 …… (ii)
I + II + III + IV + V = 84.8 × 5 = 424 ….. (iii)
From equation (ii) and (iii)
I = 80 ……  (iv)
Now, From Equation (i), (ii) and (iv)
IV + V = 175   …… (v)
From equation (i), (iii) and (v)
I + V = 164
Therefore required average= 164/2=82

Option 1:  36
Option 2:  30
Option 3:  28
Option 4:  42
Option 5:  32

Answer: 5:  32
Explanation:
Let the five consecutive even numbers be x, x+2, x+4, x+6 and x+8.
ATQ,
(x+x+2+x+4+x+6+x+8) – {( x+x+2+x+4+x+6+x+8)/5} = 128
25x + 100 – 5x – 20 = 640
20x = 640 – 80
20x = 560
X = 28
Therefore, the required third number = 32.

4) Ratio of sum of 2/5 of the present age of Anu and present age of Nila to the present age of Nila is 2:1. If the average present age of Anu, Nila and Mala is 27 years and the age of Mala after 15 years is 60% more than her present age, find the present age of Nila? 

Option 1:  16
Option 2:  20
Option 3:  24
Option 4:  12
Option 5:  8


Answer: 1:  16
Explanation:
M + 15 = 160/100 * M 5M + 75 = 8M
M = 25
A + N = 27 * 3 – 25 = 56 (2/5 A + N)/N = 2/1
2/5 * A = N A/N = 5/2
N + 5N/2 = 56 7N/2 = 56
N = 2/7 * 56 = 16

5) The sum of three consecutive odd numbers is 657. Also average of four consecutive even numbers is 84. What is the sum of smallest odd number and second largest even number? 

Option 1:  222
Option 2:  202
Option 3:  .239
Option 4:  269
Option 5:  214


Answer: 3:  .239
Explanation:
Let odd numbers is=x+2,x,x-2.
So, 3x=657
So, x=657/3=219
Now even number is y,y+2,y+4,y+6 So, 4y=84-12=72
So, y=18
Second largest even is 22
Smallest odd=217
Required sum is=239

6) Average weight of three friends A, B and C is 53 kg. Another person D joins the group and now the average is 49 kg. If another person E whose weight is 8 kg more than D, joins the group replacing A, then average weight of B, C, D and E becomes 51 kg. What is the weight of A (in kg)? 

Option 1:  40 kg
Option 2:  35 kg
Option 3:  45 kg
Option 4:  37kg
Option 5:  42kg


Answer: 4:  37kg
Explanation:
Average = Total/number of terms
Calculation
A + B + C = 53 × 3 = 159 kg
A + B + C + D = 49 × 4 = 196kg      ---- (I)
⇒D = 196 – 159 = 37 kg
So, E = D + 8
E = 37 + 8 = 45 kg
Now,
B + C + D + E = 51 × 4 = 204 kg      ---- (II)
From equation (I) and (II),
E – A = 204 – 196 = 8 kg
⇒45 – A = 8
⇒A = 37 kg

If one more teacher weighing 54 kg is added, then the average weight of the class increases by 3 kg over the original average. What is the original average weight (in kg) of the class? 

Option 1:  50
Option 2:  30
Option 3:   20
Option 4:  60
Option 5:  40

Answer: 2: 30

Explanation:

Let the students in a class be x
And average weight of class is y
ATQ,
(xy+72)/(x+1) = y+2
⇒ xy + 72 = xy + 2x + y + 2
⇒ 2x + y = 70 ……(i)
Now, another teacher joined the class
(xy+72+54)/(x+2) = y+3
⇒ xy + 126 = xy + 3x + 2y + 6
⇒ 3x + 2y = 120 …….(ii)
By equation (i) and (ii),
Number of students
X = 20
∴ Original average weight,
Y = 30 kg
