Directions (1-5): In the given table data is given about the shop.Some electronic goods are  sold by a shop. Some data is missing. Study the table carefully and answer the questions based on data in table and particular questions.

  1. What is the ratio of the cost price of mobile and cost price of laptop?
    A)  4:2
    B)  5:3
    C)  6:4
    D)  5:4
    E) None of these
    View Answer
      Option D
    Solution:
    Cost Price of mobile  = 25000 * 100/ (100+25) = 20000
    Cost Price of laptop = 20000 * 100/ (100+25) = 16000
    Required Ratio = 20000 : 16000 = 5 : 4
  2. Market Price of T.V is how much percent more than the cost price of T.V ?
    A)  37.5 %
    B)  35.5%
    C)  36.0%
    D)  40.7%
    E)  32.6%
    View Answer
     Option A
    Solution:
    Amount of profit on T.V  = 2000
    Cost Price = 2000* 100/10 = 20000
    Selling Price = 20000 + 2000 = 22000
    Market Price = Selling Price  * 100 / (100 – Discount%)
                                =  20000 * 100 /80 = 27500

    Required Percentage = [(27500 -20000) /20000] * 100 = 37.5%
  3. What is the ratio between the percentage of profit and percentage of discount of Mobile ?
    A)  3:2
    B)  4:3
    C)  2:3
    D) 4:5
    E) 4:3
    View Answer
      Option C
    Solution:
    Percentage of profit on Mobile  = 25%
    Percentage of discount on Mobile = [40000 – 25000/40000]*100
    .                                                                    = 37.5%
    Required Ratio = 25 : 37.5
    .                               = 2 : 3
  4. Selling Price of D.V.D is what percent of cost price of A.C ?
    A)  5.6%
    B)  7.2%
    C)  5.3%
    D)  3.4%
    E) None of these
    View Answer
     Option C
    Solution:
    Market Price of D.V.D = 500 * 100/20 = 2500
    Selling Price of D.V.D = 2500 – 500 = 2000
    Selling Price of A.C = 50000 * 60 / 100 = 30000
    Cost Price of A.C = 30000 * 100/80 = 37500
    Required Percentage = (2000/37500)*100 = 5.3%
  5. What is the amount (in Rupees) of profit /loss  of shop by selling all electronic goods ?
    A)  5000
    B)  5700
    C)  5600
    D) 5200
    E)  5500
    View Answer
      Option B
    Solution:
    Selling Price of A.C = 50000 * 60/100 = 30000
    Loss on A.C = 30000 * 100/80 – 3000 = Rs.7500
    Market Price of D.V.D  = 500 * 100 /20 = 2500
    Selling Price of D.V.D = 2500 – 500 = 2000
    Profit on D.V.D =2000 – 1800 = Rs.200
    Profit on T.V = Rs. 2000
    Profit on Mobile = 25000 – 25000 * 100/25 = Rs. 5000
    Profit on Laptop = 20000 – 20000 * 100 / 125 = Rs. 4000
    Profit on Radio = 10,000 * 20 /100 = Rs.2000Total Profit =  -7500 +  200 + 2000 + 5000 + 4000 + 2000
    = Rs. 5700 

Directions (6-10): The given tables show the time taken by filling and emptying pipes to fill and empty a tank respectively. Some data is missing. Study the table carefully and answer the questions based on data in table and particular questions.

  1. Pipes B and D are to fill the tank. They both are opened. After 8 minutes pipe R was also opened. It took 3 11/39 minutes more to fill the tank. In how much time pipe R can empty the tank?
    A) 24 minutes
    B) 48 minutes
    C) 50 minutes
    D) 60 minutes
    E) 72 minutes
    View Answer
      Option C
    Solution:
    B+D = 1/25 + 1/40 = 13/200
    Worked for 8 minutes, so did 13/200 * 8 = 13/25 work
    So 200/13 – 8 = 96/13 minutes left to complete work,
    But after R was opened, it took 3 11/39 minutes more, means total 96/13 + 128/39 = 416/39 = 32/3 minutes
    So now  B+D – R
    13/25  + (13/200 – 1/R) * 32/3 = 1
    Solve, x = 50 minutes
  2. Pipes A, C and D are opened to fill a tank. After 10 minutes A and D were closed and C had to fill the remaining tank. But accidentally at the same time pipe Q was also opened which was closed after 3 minutes. Now C filled the tank. If pipe Q was not opened, how much time would have been saved?
    A) 1 minute
    B) 5 minutes
    C) 3 minutes
    D) 4 minutes
    E) 2 minutes
    View Answer
      Option E
    Solution:
    A+C+D = 1/24 + 1/48 + 1/40 = 7/80
    Worked for 10 minutes, so filled 7/80 * 10 = 7/8th of tank
    Now C and Q are opened for 3 minutes — (1/48 – 1/72)* 3 = 1/48th filled now
    So 7/8 + 1/48 + 1/48 *x = 1
    Solve,  x = 5 minutes
    So total time = 10+3+5 = 18 minutes
    If Q was not opened::
    1/8th of tank was to be filled by C
    So 1/48 * u = 1/8,
    Solve, u = 6
    So total time here = 10+6 = 16 minutes
    So time that would have been saved = 18-16 = 2 minutes
  3. 11/40th of a tank was filled. Pipes C and D were opened. After some time pipe P was also opened. Pipe P was closed after time equal to the time it was opened at the starting . If after closing pipe P, the tank was filled in 6 minutes, find what fraction of tank was filled by pipe C?
    A) 7/8th
    B) 3/8th
    C) 2/7th
    D) 5/7th
    E) None of these
    View Answer
      Option B
    Solution:
    C+D = 1/48 + 1/40 =  11/240
    Let after x minutes P was opened, so P was opened for x minutes [as given] So
    11/40 + (1/48 + 1/40) * x + (1/48 + 1/40 – 1/60)*x + (1/48 + 1/40) * 6 = 1
    OR  11/40 + (1/48 + 1/40) * 2x – 1/60 * x + (1/48 + 1/40) * 6 = 1
    Solve, x = 6 minutes
    So C was opened for 2x+6 = 18 minutes
    So filled 1/48 * 18 = 3/8 of tank
  4. Pipe D was to fill a tank. To increase its efficiency, pipe A and C were opened for 2 minutes each starting with pipe A, then C and so on. This procedure ran for 16 minutes, after which pipe A and C were closed. Accidentally pipe S was opened and now it took 4 minutes more to fill the tank. Find in how much time pipe S can empty 3/40th of tank.
    A) 11 minutes
    B) 12 minutes
    C) 3 minutes
    D) 7 minutes
    E) 6 minutes
    View Answer
      Option E
    Solution:
    For 2 minutes A and D. So
    (1/24 + 1/40)* 2= 2/15
    For next 2 minutes C and D. So
    (1/48 + 1/40)* 2= 11/120
    So in 4 minutes — 2/15 + 11/120 = 9/40
    Procedure ran for 16 minutes, so multiply by 4 both sides
    In 16 minutes, tank filled = 9/40 * 4 = 9/10
    Now 1/10 tank left which D can fill in 4 minutes, but with D and S opened, took 4 more minutes, so 8 minutes
    So (1/40 – 1/x) * 8 = 1/10
    Solve, x = 80 minutes
    Full tank in 80 minutes so 3/40th in 3/40 * 80 = 6 minutes
  5. To fill an empty tank all filling pipes A, B, C and D are opened one by one in same order. A and C are opened for 4 minutes each while B and D for 5 minutes each. In this way, in how much time the tank will be filled (approximately)?
    A) 30 minutes
    B) 32 minutes
    C) 27 minutes
    D) 22 minutes
    E) 35 minutes
    View Answer
      Option A
    Solution:
    A for 4 minutes = 1/24 * 4  = 1/6
    B for 5 minutes = 1/25 * 5  = 1/5
    C for 4 minutes = 1/48 * 4  = 1/12
    D for 5 minutes = 1/40 * 5  = 1/8
    So in 18 minutes (4+5+4+5), tank filled is 1/6 + 1/5 + 1/12 + 1/8 = 23/40
    Next A’s turn for 4 minutes = 1/6
    Next B’s turn for 5 minutes = 1/5
    Filled now = 23/40 + 1/6 + 1/5 = 113/120
    Now 7/120 is left
    Now C’s turn, full tank in 48 minutes, so 7/120 in  48 * 7/120 = 14/5 minutes
    So total = 18 + 4 + 5+ 14/5 = 27 + 3 = 30 mins approx

      c =48
      d=40
      p =-60
      lcm =240 =>c =5 ,d =6 p =-4
      now 11/40 part =11/40*240 =66
      now let p is opened after x min frm c and d now given condition is that opening tym of p = to closing tym
      => 66 +11x +(11-4)x +6*11 =240
      =>132 +18x =240 =>18x =108 =>x =6min
      now this is the closing tym => until this time c and both works 2x (x before p +x with p) time =>totl time taken by c =totl tym taken by d =2x+6 =2*6+6 =18min

            Two persons Raj and Ramu started working for a company in similar jobs on January 1, 1991. Raj’s initial monthly salary was Rs 400, which increases by Rs 40 after every year. Ramu’s initial monthly salary was Rs 500 which increases by Rs 20 after every six months. If these arrangements continue till December 31, 200. Find the total salary they received during that period.

            ans 152400

          6. $~$PrAdeEP$K$~$~$

            raj’s salary increment
            => 400 +440+————————-+upto 10 terms
            now sum to n terms of an ap is given by
            s(n) =n/2(2a+(n-1)d)
            => r(s) =10/2(800+9*40) =5800
            => totl anuual salary incremnt =12*5800 =69600rs
            now ramu’s salary increment
            =>500+520+————————+upto 20 terms(1 year =2 half months so 10year = 20 half months)
            =>ra(s)=20/2(1000+19*20) =13800
            => totl monthly salary inc.=6*13800 =82800
            => totl money recieved =69600+82800 =152400rs
