Q:

Subbu purchased a tape recorder at 9/10 of its selling price and sold it at 8% more than its selling price. His gain is

Answer

Let S.P = x then C.P = \inline \frac{9x}{10}


Selling price received by subbu = (108% of x)


                                            = \inline \frac{108}{100}x=\frac{27}{25}x


Gain= \inline (\frac{27}{25}x-\frac{9}{10}x)=\frac{9}{50}x


Hence gain% = \inline (\frac{9x}{50}\times \frac{10}{9x}\times 100) = 20%

Answer

1. Answer : 4


Explanation : Required ratio = 10+2+510+15+10=173512=1:2 


 


2. Answer : 1


Explanation : 


A to B Speed =140×35  = 84  


B to C Speed = 91×34 = 68.25 


C to D Speed = 149×60103 = 86.796  


D to E Speed = 88×34 = 66  


E to F Speed =  106×45= 84.8  


F to G Speed = 1762 = 88  


G to h Speed =  110×45= 88  


Average speed of entire trip = 84+68.25+86.796+66+84.8+88+887 =80.83 


 


3. Answer : 3 


Explanation :  Total half time = 10 + 2 + 5 + 10 + 15 + 10 = 52 


Total half time, if the train stops at each city for 50% more=52×150100=78 


Train will arrive at city H after departing from city A = 18.25 + (78 - 52 )=18.25 + 26=18.51


 


4. Answer : 2 


 Explanation : Average speed = 84+68.25+86.796+66+84.8+88+887=80.83=81 km/hr


 


5. Answer : 1 


Explanation :  Required percentage of time = 1.40+1.20+1.43+1.20+1.15+2+1.1518.25-7×10010.2311.25×100 = 91.8 %

Q:

Two trains are running at 40 km/hr and 20 km/hr respectively in the same direction. Fast train completely passes a man sitting in the slower train in 5 seconds. What is the length of the fast train?

A) 27 7/9 mts B) 25 8/7 mts
C) 21 1/4 mts D) 22 mts
 
Answer & Explanation Answer: A) 27 7/9 mts

Explanation:
Relative speed = (40 - 20) km/hr = ( 20 x 5 ( m/sec = ( 50 ( m/sec.
18 9
Therefore Length of faster train = ( 50 x 5 ( m = 250 m = 27 7 m.

5. What is the sum of the borrowings of all five companies ?

1. Rs.146 lakh      2. Rs.14.6 lakh      3. Rs.14.6 crore      4. None of these

Answer

1. Answer : 4


Explanation : Let the borrowing of Company A = x


Interest of Company A = 234000


Rate of Interest = 18% 


x×18100=234000     x=1300000


 


Let the borrowing of Company B = y 


Interest of Company B = 576000


Rate of interest = 24%


y×24100=576000     y=2400000 


 Required difference = y - x = 2400000 - 1300000 = Rs. 1100000 


 


 


2. Answer : 2


 Explanation : 


 Let the profit of Comapny B = 100%


 Dividend Payout ratio(%) of B = 19.60


 Remaining percent i.e retained earning = 100 - 19.60 = 80.4%


 According to question, 80.4% = Rs.402 lakh


 100% = Rs.500 lakh


 Therefore,  Total dividend paid by Company B = 500 - 402 = Rs. 98 lakh


 


 Let the profit of company D = 100%


 Dividend payout ratio (%) of D = 32.50 


 Remaining percent i.e retained earning = 100 - 32.50 = 67.5% 


 According to question, 67.5% = Rs. 270 lakh 


 100% = Rs. 400 lakh


 Therefore, Total dividend paid by company D = 400 - 270 = Rs. 130 lakh 


 Required difference = 130 - 98 = Rs. 32 lakh 


 


 


3. Answer : 3


Explanation : 


Let the profit of Company C = 100% 


Dividend payout ratio of C = 8.75% 


Remaining percent i.e, retained earning = 100 - 8.75 = 91.25 


According to question, 91.25% = Rs. 365 lakh 


100% = Rs. 400 lakh 


Therefore, Profit of C = Rs. 400 lakh


 


Let the profit of company E = 100% 


Dividend payout ratio of E = 28% 


Remaining percent i.e retained earning = 100 - 28 = 72% 


According to question, 72% = Rs.216 lakh 


100% = Rs.300 lakh


Therefore, Profit of E = Rs. 300 lakh 


Required percentage = 100400×100 = 25% less


 


 


4. Answer : 3


 Explanation : 


 Profit made by company A = Rs. 200 lakh


 Profit made by company B = Rs. 500 lakh 


 Required Sum = 200 + 500 = Rs. 700 lakh


 


  


5. Answer : 4 


Explanation : 


 Required Sum = 1300000 + 2400000 + 810000 + 1600000 + 1200000 = 7310000 = Rs. 73.1 lakh
