2. c
3. c
4. b

14. b
15. d


Solution

1.  Since  veer calculates his profit percentage on Selling price so ,
CP = SP-25/100 SP = 75/100 SP = 3/4 SP
&vipin calulates his profit percentage on Cost price, So
SP = CP+25/100 CP= 5/4 CP or CP = 4/5 SP
As, Difference in Profit =100
SP/4 - SP/5 = 100
So, Selling Price = 2000

2.  Final Price Paid by customer = 800*(90/100) *(95/100) * (105/100) = 718.20

3. New SP= 6500+ 15% of 6500 = 7475
 Old Cost price = 6500 -12% of 6500 =5720
New Cost Price = 125% of 5720 = 7150
% Profit = (7475-7150)/ 7150 *100 = 4.5%

4.  Let the initial capital is X 
After one year 3/4 of X will be donated aur utna hi hath me bachega 
After 2nd yr 9/16 of X will be donated ...& same 
After 3rd yr 27/64 of X will be donated and the same in hand 
27/64 of X = 16875
calculate x= 40000
Amount denoted in 2nd year =9/ 16 of X= 22500

5. Ratio of material's 2 : 3 : 4 : 5
Let is value be 20 , 30, 40, 50 so total sum = 140
Now, there is + 10 % increase in cost of P, 20 + 2 = 22
- 20 % decrease in the cost of Q , 30 - 6 = 24
- 30 % decrease in the cost of R , 40 - 12 = 28
+ 40 % increase in the cost of S , 50 + 20 = 70
Now, total sum of latest cost = 22+ 24 + 28 + 70 = 144
% change of Cost = (144-140)/140 * 100 = 2.85%

6.  Let X is the initial population of Male and Y be the initial population of Female
X + Y = 5500 .........(1)
If the number of males increases by 11 % and the number of females increases by 20 %, then
(111/100 )X+ (120/100) Y = 6330
1.11 X + 1.2 Y = 6330 , On putting the value of X from equeation (1)
1.11 ( 5500 - Y ) + 1.2 Y = 6330
Y = 2500, Population of females in town.

7. Let the speed of a man in still water be x km/hr and the speed of a stream be y km/hr. If he takes t hours more in upstream than to go downstream for the same distance,
 the distance  = (x^2 - y^2)t/ 2y Km
x = 8 km/hr
y = 3 km/hr
t = 3 hours
As per the formula,
Distance = 27.5 Km.

8.  Amount after 3 years on Rs.20000 at 10% compound interest
= 20000( 1+ 10/100)^3= 26620.............(1)
He paid Rs.2000 after 1st year.
Hence Rs.2000 and its compound interest for 2 years (i.e., amount on 2000 after 2 year) need to be reduced from (1)
Similarly, he paid Rs.2000 after 2nd year.
Hence Rs.2000 and and its compound interest for 1 year (i.e., amount on 2000 after 1 year) need to be reduced from (1)
Similarly, he paid Rs.2000 after 3rd year.
Hence this Rs.2000 also need to be reduced from (1)
Hence, remaining amount=  26620 - 2000(1+10/100)^2 - 2000(1+10/100) - 2000 = Rs. 20000
i.e, he still owes Rs.20000 even after three installments.

9. Suppose pipe A alone takes x hours to fill the tank.
Then, pipes B and C will take x/2 and x/4hours respectively to fill the tank.
1/x+2/x+4/x = 1/5
on Solving,
 x = 35 hrs.

10.  A, B, C do it in 20, 30 , 40 min respectively Let total work be 120
Efficiency of A,B,C = 6,4,3 respectively
First 5 min work = 13* 5 = 65
remaining = 120-65 = 55
next 6 min work = 7*6 = 42
Remaining = 13
Now, 120 work is done by leak in 60 minutes
Leak's efficiency = 120/60 = -2(as it empties the tank)
Leak +C = 3-2 = 1
time taken = 13/1 = 13 minutes
Total time taken = 5+6+13 = 24 Minutes

11. R=(100/9)^1/2 =3.33%

12.  P(r/100)^2= 40
P(r/100)^2 ×(300+r)/100 =61
On Solving P= 8000

13. P[(1+r/100)^2 -1]= 272 ----(1)
P[(1+r/100)^3 -1]= 434-----(2)
Consider 1+r/100 =a
On dividing eqn (2) by (1)
So (a3-1)/ (a2-1) = 434/272
On solving a=9/8
So 1+r/100 = 9/8
So  r= 12.5%

14.  1st year loss = 1500
Price after 1st year = 28500,
2nd year profit = 2850
Price after 2nd year =31350
Profit in 3rd year = 3918.75
So net profit during 3 years = 3918.75+ 2850 – 1500= 5268.75
So option E is true

15. Final ratio of Dettol and water = (1-1/3)^4/{1-(1-1/3)^4}  = 16: 65
