Aptitude and Reasoning Questions

Q:

In the following question, two equations numbered 1 and 2 are given. You have to solve both the equations and determine the relation between a and b.

1.  5a2-18a+9=0

2.  3b2+5b-2=0

A) a >= b B) a <= b
C) a < b D) a > b
 
Answer & Explanation Answer: D) a > b

Explanation:

From solving 1 and 2 we get,

 

1.

5a(a-3)-3(a-3) = 0

 

(5a-3)(a-3) = 0

 

a = 3 or 3/5

 

2. 

 

3b(b+2)-1(b+2) = 0

 

b = -2 or b = 1/3

 

Here when a = 3, a > b for b = -2 and b = 1/3

 

when a = 3/5. a > b for b = -2 and b = 1/3.

 

Hence, it is clear that a > b.

A) No gain - No loss B) Loss 10%
C) Gain 12.5% D) Gain 10%
 
Answer & Explanation Answer: D) Gain 10%

Explanation:

Given that mill worth originally =3ooooo

Depreciation for 1 yr =300000x5/100= Rs. 15000

Then, depreciation for 5yrs = Rs. 75000

Value after 5yrs = 300000 - 75000 = Rs. 225000

Given Selling Price of the mill = Rs. 250000

Sp > CP

Gain = 250000 - 225000 = Rs. 25000

Gain% = 25000/250000 x 100 = 10%.
