Answer

From the assumption and trial and error method,


last three digits sum must leave the same digit as the answer. It is possible only if the answer must be units digit number leaving tens digit as carry.


And the possible 3rd digit is 5. Since 5 + 5 + 5 = 15 


Now, 2nd step is  1 + x + x + x = 5


=> 3x = 4


It is possible with x = 8. 8 + 8 + 8 + 1 = 25 leaving 2 as carry. 


Now, 3rd step is 2 + x + x + x = 5 => x = 1


 


Hence, the three dgits are 1, 8, 5.


185 + 185 + 185 = 555.

Q:

The ratio of K’s and M’s ages is 4: 5. If the difference between the present age of M and the age of K, 5 years hence is 3 years, then what is the difference and total of present ages of K and M?

A) 8, 72 yrs B) 16, 65 yrs
C) 12, 84 yrs D) 10, 60 yrs
 
Answer & Explanation Answer: A) 8, 72 yrs

Explanation:

Let the present ages be K,M

Given K/M = 4/5

5K - 4M = 0 ......(1)

Also given that,

M - (K + 5) = 3

M - K = 8 .........(2)


Then, by solving (1) & (2)

M = 40 yrs and K = 32 yrs

Hence, Total of ages = 40 + 32 = 72 yrs

Difference of ages = 40 - 32 = 8 yrs.

Q:

Resistance of human body in dry condition

A) 10 ohm B) 1000 ohm
C) 10000 ohm D) 100000 ohm
 
Answer & Explanation Answer: D) 100000 ohm

Explanation:

Under dry conditions, the resistance offered by the human body may be as high as 100,000(10^5) Ohms.

 

Depending on the person, a rough value for the internal resistance of the human body is 300-1,000 Ohms. The skin's resistance is much lower if it is wet or burnt/blistered.



There are a lot of factors involved and not every person has the same electrical resistance. For instance, men tend to have lower resistance than women.

Within the body, the tissues with the greatest resistance are bone and fat - nerves and muscle have the least resistance.

Q:

Which statement fits the Frontier Ethic?

A) Recycle plastic B) Help those in need
C) He who has more toys wins D) Walk lightly on Earth
 
Answer & Explanation Answer: C) He who has more toys wins

Explanation:

Frontier Ethic is Spending Earth's assets at the cost of losing resource capital. A frontier ethic assumes that the earth has an unlimited supply of resources. It is the notion of disregarding the Earth for the benefit or gain of man.

If resources run out in one area, more can be found elsewhere or alternatively human ingenuity will find substitutes. This attitude sees humans as masters who manage the planet. It is completely Anthropocentric.
