   Option B
   Solution:
   .                             CP………………SP
   Profit 25% =1/4     4…………………5
   LOSS 25%=1/4      4…………………3
   4*4 = 16 …………5*3 = 15
   .                                      (-1)
   15 == 24,000
   1 == Rs1600 loss

   6600/60=110 paisa
   B……………………..G
   160………………….100
   .              110
   10……………………….50
   1………………………….5
   5/6*60 =50 GIRLS
3. Two persons cover the same distance at the speed 35kmph and 40kmph respectively. Find the distance travelled if one person takes 15min more than the other?
   A) 80km
   B) 60km
   C) 50km
   D) 70km
   E) 90km
   
   View Answer

   Option D
   Solution:
   speed ratio- 35 : 40
   .                     7 : 8
   time ratio- 8 : 7
   .                 (+1)=15
   8=120min
   So 35*2hr= 70km
4. A sum becomes 8000 in 2yrs and 1600 in 4yrs at compound interest. Find the sum (in Rs)?
   A) 4000
   B) 6000
   C) 7000
   D) 5600
   E) 5000
   
   View Answer

   Option A
   Solution:
   In this case when difference between time period is same then
   x : y = y : z
   x/8000 = 8000/16000
   x= 4000
5. If a student gets 30% marks in an examination then he passes by 10 marks and if he gets 35% marks then he passes by 30 marks . find how many marks he needs to pass?
   A) 100

   D) 110
   E) 150
   
   View Answer

   Option D
   Solution:
   (+10)……..(+30)
   30%………..35%
   35-30 = 5%
   5% = 20
   1% = 4
   30% = 120
   Pass marks = 120-10 =110
6. Two person A & B walk from P to Q at a distance of 38km at 8kmph and 11kmph respectively. B reaches Q and returns immediately and meets A at R. find the distance from P to R?
   A) 36km
   B) 34km
   C) 32km
   D) 30km
   E) 38km
   
   View Answer

   Option C
   Solution: in this case both A and B cover double distance together, so time taken by them
   2*38/(8+11)= 4hrs
   So distance from P to R = 8*4 = 32kmph
7. A & B invest 10,000 and 11,000 respectively in a scheme. After 6months A withdrawal 20% of his investment and B add 9(1/11)% of his investment. If after one year their profit is rs8200. Find the share of B ?

   View Answer

   Option B
   Solution:
   10000        11000
   .          10 : 11
   .          *6 *6
   .          60 66……………………..(1)
   A = 10000 – 2000= 8000
   B = 11000+ 1000 = 12000
   8000 : 12000
   8 : 12
   *6 *6
   48 72………………………………………..(2)
   Add (1) and (2)
   60+48= 108
   66+72= 138
   108 : 138
   18 : 23
   B’s share = 23/41 *8200 =4600
8. A and B separately complete a piece of work in 25days and 40days respectively. They worked together for some time then A left the work. If B completed the remaining work in 14days, then A worked for?
   A) 12days
   B) 10days
   C) 14days
   D) 8days
   E) 13days
   
   View Answer

   Option B
   Solution:
   A = 25……..8
   B = 40………5………….(LCM=200)
   A+B = 13
   B’s 14 days work = 5*14= 70
   Means A&B together done 130 work, so together they do 13 work in a day….so 130/13=10days
9. A rectangular sheet with dimensions 22m*10m is rolled into a cylinder so that the smaller side becomes the height of the cylinder. What is the volume of the cylinder so formed ?
   A) 385m²
   B) 375m²
   C) 365m²
   D) 355m²
   E) 395m²
   
   View Answer

   Option A
   Solution:
   According to method
   Volume = H *(other side)²/4∏
   = 10*(22)²/(4*22/7)
   = 385m²
   Best approach .. see ANS will be divisible by 11. So our ANS is A
10. Find the volume of a cylinder which has height of 14m and a base of radius 3m. also find the curved surface of the cylinder?
    A) 392m³,262m²
    B) 396m³,264m²
    C) 398m³,274m²
    D) 399m³,276m²
    E) 399m³,226m²
    
    View Answer

    Option B
    Solution:
    ANS will be divisible by 11.
    See …. 396..
    Add alternate number and subtract the solution with middle number..
    3+6=9
    9 -9 =0
    If the difference is 0 or multiple of 11 then it is divisible of 11.
