NTT Data Averages Quiz -1

Total weight = (10 x 23.75) + (7 x 34.25) = (237.5 + 239.75) = 477.25

Total no of  boxes = 10 + 7 = 17

Average = 477.25/17 = 28.07

Total sale for 4 months = (1300 + 1700 + 1450 + 1200)  = 5650

Needed sale = (2300 x 5) – 5650

= Rs. 11500 – 5650

= 5850

Let us assume the numbers are x, x+2, x+4, x+6, and x+8.

=> [x + (x + 2) + (x + 4) + (x + 6) + (x + 8)] / 5 = 71

=5x + 20 = 355

=>X= 67

 

Subtracting the two numbers,

= (67 + 8) – 67

= 8

Let us assume the average after the 17th inning be = P

After the 16th inning, average =   P -3

16 (P-3) + 83 = 17 P

=>P= 83-48

=>P= 33

The removed number is = (25 x 5) – (20 x 4)

= 125 – 80

= 45

Let, third number be = a

Second number be = 2a

First number be = 2 x 2a = 4a

So, average = (a+2a+4a)/3

=>91=7a/3

=>a = 13 x 3 = 39

Hence, first number = 4a = 4 x 39 = 156

Increased age = (8 x 2) years= 16 years.

Sum of the ages of the two other women = (21 + 23 +16) years = 60 years

The average age of the two other women = (60/2) = 30 years

Let us assume the total number of bags be ‘p’

Therefore, 9000p = (12000 x 7) + 6000 (p - 7)

=> 3000p = 42000

=>p= 14.

Let us assume their prices to be 3x, 5x, and 7x.

Therefore, 3x +5x + 7x = (12000 x 3)

=>15 x = 36000

=>X= 2400

Cost of the cheapest computer = 3 x 2400 = Rs. 7200

Average number is same as the middle number

Third number is 113

Five consecutive odd numbers are 109,111,113,115,117

Descending order is 117,115,113,111,109

Fourth number in descending order is 111
