- Question
- What is the middle number of 7 consecutive whole numbers?
I. Product of number is 702800.
II. sum of the the number is 105.
Options- A. if statement I alone is sufficient to answer the question.
- B. if statement II alone is sufficient to answer the question.
- C. if both statement I and II together are necessary to answer the question.
- D. if both statement I and II together are not sufficient to answer the question.
- Correct Answer
- if statement II alone is sufficient to answer the question.
ExplanationLet the 7 consecutive whole numbers be (n ± 3), (n ± 2), (n ± 1), n.
Now i we consider Statement I alone
Product of these 7 integers = 702800
Since 702800 = 24 52 (251)(7), it cannot be the product of 7 consecutive whole numbers. Hence I alone is insufficient.
Now if we consider Statement II alone
Given that their sum = 105 = 7n or n = 15 and then 7 consecutive integers are 12, 13, 14, 15, 16, 17, 18 So, II alone is sufficient. - 1. If the total amount spent during the year 1999 was $ 46000, the amount spent on food was :

Correct Answer: $ 10580
Explanation:
Correct Answer: 10 : 13
Explanation:
Let expenditures of Company B in 2003 and 2004 are Rs. 5x and Rs. 7x respectively; then
their income in 2003, I1= 5x + 40/100 x 5x = Rs. 7x
Also their income in 204, I2 = 7x + 30/100 x 7x = Rs. 91x/10
Hence, the required ratio = 7x : 91x/10 = 10 : 13
Correct Answer: A
Explanation:
As per given table , we can see that
The minimum number of student participated in extra curriculum in All 7 collages is collage A and 65 student.

Sales in the year 2005 = 10 billion $
Sales in the year 2006 = 6 billion $
Sales in the year 2007 = 6 billion $
Sales in the year 2008 = 5 billion $
? Required total sales = Sum of all sales from 2005 to 2008
Required total sales = $ (10 + 6 + 6 + 5) billion= $ 27 billion
Correct Answer: 1 : 4
Explanation:
Required ratio = (440 - 410) : (570 - 10 - 440) = 30 : 120 = 1 : 4
Correct Answer: 4.4 cores
Explanation:
Average number of units sold = ( Units sold in 2004 + Units sold in 2005 + Units sold in 2006 + Units sold in 2007 + Units sold in 2008 ) / 5
Average number of units sold = (3.5 + 4 + 5 + 3 + 6.5)/5 = 22/5 = 4.4 crores
Correct Answer:
Explanation:
Correct Answer: 85
Explanation:
In 2008, the number of students studying Arts and commerce together
= (12 + 22)/100 x 35000 = 34 x 350 = 11900
In 2009, the number of students studying Arts and Commerce together
= (11 + 24)/100 x 40000 = 35 x 400 = 14000
Hence, required percentage = 11900/14000 x 100 = 85%
Correct Answer: 3700
Explanation:
Expenditure increased = Expenditure in 1997 ? 98 - Expenditure in 1993 ? 94
Expenditure increased = 8800 ? 5100 = 3700.
