Q:

A person sold two cows each for Rs.9900. If he gained 10% on one and lost 20% on the other, then which of the following is true?

A) He Gained Rs. 200 B) He lost Rs. 200
C) He neither gained nor lost D) None of the above
 
Answer & Explanation Answer: D) None of the above

Explanation:

The CP of profitable cow  = 9900/1.1 = 9000

 

and profit = Rs. 900

 

The  CP of loss yielding cow = 9900/0.8 = 12375

 

and loss = Rs. 2475

 

so, the net loss = 2475 - 900 = 1575

Q:

A person's present age is two-fifth of the age of his mother. After 8 years, he will be one-half of the age of his mother. How old is the mother at present ?

A) 36 yrs B) 38 yrs
C) 40 yrs D) 42 yrs
 
Answer & Explanation Answer: C) 40 yrs

Explanation:

Let the mother's present age be x years.

Then, the person's present age = 2/5 x years.

(2x/5 + 8) = 1/2 (x + 8)

2(2x + 40) = 5(x + 8) => x = 40.

Q:

For any two numbers m , n ; (m+n) : (m-n) : mn = 7: 1: 60 . Find the value of 1/m : 1/n

A) 4:3 B) 8:7
C) 3:4 D) 7:8
 
Answer & Explanation Answer: C) 3:4

Explanation:

m+nm-n=7xx mn=4x3x  

 

Again   mn=12x2 

 

and         mn =60x  

 

so, 60x=12x2 x=5    

 

=>  m= 20  and    n= 15

 

Hence,    1m:1n=120:115=3:4

Q:

What is the probability of getting at least one six in a single throw of three unbiased dice?

A) 1/36 B) 91/256
C) 13/256 D) 43/256
 
Answer & Explanation Answer: B) 91/256

Explanation:

Find the number of cases in which none of the digits show a '6'.

i.e. all three dice show a number other than '6', 5×5×5=125 cases.

Total possible outcomes when three dice are thrown = 216.

The number of outcomes in which at least one die shows a '6' = Total possible outcomes when three dice are thrown - Number of outcomes in which none of them show '6'.

=216−125=91

The required probability = 91/256
