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

Consider the following grouped frequency distribution:

  x           f

0-10       8

10-20     12

20-30     10

30-40      p

40-50      9

 

If the mean of the above data is 25.2, then what is the value of p?

 

A) 9 B) 10
C) 11 D) 12
 
Answer & Explanation Answer: C) 11

Explanation:
Mean = (sum of fixi/ (sum of f) = (8*5 + 12*15 + 10*25 + P*35 +9*45) / (8+12+10+P+9) = 25.2
(875 + 35P)/(39+P) = 25.2
P = 11

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
