Wrong assumption (Question: 113688.2 )

0.9x = 360 is a wrong assumption as in that case the increment will be 9% instead.
1.1x = 360 is a correct assumption.

Question:

DIRECTIONS: Study the following data carefully and answer the questions that follow:

Year wise and sector wise distribution of Graduates employed

Year of Graduation	Percentage of graduates employed
Year of Graduation	FMCG Sector	Finance Sector	Consultancy
1999	25	15	25
2000	30	33	24
2001	22	23	25
2002	32	33	15
2003	15	25	20
2004	35	25	20
2005	15	35	20
2006	10	45	25

Sector wise distribution of Average annual salary (in Rs.)

-	Average annual Salary (Rs.)
Field	1999	2006
FMCG Sector	72,000	90,000
Finance Sector	90,000	1,20,000
Consultancy	1,00,000	1,50,000
Others	75,000	1,00,000

If the total number of graduates in 2006 was 360,000 which is a 10 percent decrease from 1999, then the difference in the number of graduates who joined the Finance sector in 1999 and 2006 is (in 000):

Options:

A) 162

B) 102

C) 60

D) 86

E) None of these

Solution:

Ans: (b)

Let the number of graduates in 1999 = x

∴ 0.9x = 360 ⇒ x = 400

1979 1986

Total 400 360

Finance 60 162

Hence 162 – 60 = 102

Alternative:

Let the no of graduates in 1999 = x

x-(x*10%)=36000

9x=360000

x=40000

1999 2006

Total 40,000 36,000

Finance 60,000 1,62,000

Hence Difference = 1,62,000 - 60,000

= 102000

= 102 (in 000)
