  6. An amount of Rs. 16600 is divided equally and each is invested at two different rates of interest. The difference between the interests got after 4 year is Rs. 700. What is the difference between the rates of interest?
    4.2%
    3.5%
    3.13%
    2.10%
    1.5%
    Option D
    Let the 2 different rates be x and y respectively. Difference between the interests is Rs 700.
    = [8300 × 𝑥 × 4]/100 – [8300 × 𝑦 × 4]/ 100 = 700
    = 33200x-33200y =700×100
    = 33200(x – y) = 70000
    x-y = 2.10%

     

  7. Mrs. Mary decided to distribute pens among A,B,C and D in the ratio 3:4:6:5 resp. But mistakenly she distributed pens among them in the ratio of 5:8:4:7 resp., So, A and B got 3 and 8 pens more resp. The number of pens received by D is what % more than the number of pens she was expected to receive ?
    10%
    9%
    7%
    8%
    5%
    Option E
    Number of pens expected to receive by A,B,C and D = 3x,4x,6x and 5x.
    Number of pens received by A,B,C and D = 5x,8x,4x and 7x.
    ATQ, 8y – 4x = 8 And 5y – 3x = 3
    Solving both the equations,we get x = 4 and y = 3
    Number of pens expected to receive by D = 5*4 = 20
    Number of pens received by D = 7*3 = 21
    Required% = (21-20)/20*100% = 5%

     

  8. In an examination, a student scores 4 marks for every correct answer and loses 1 mark for every wrong answer. If he attempts all 60 questions and secures 130 marks, find the no of questions he attempts correctly.
    25
    38
    45
    40
    30
    Option B
    Let the number of correct answers be X.
    Number of incorrect answers = (60 – X).
    4x – (60 – x) = 130
    => 5x = 190
    => x = 38

     

  9. A train travelling at a speed of 75 mph enters a tunnel 3(1/2) miles long. The train is 1/4mile long. How long does it take for the train to pass through the tunnel from the moment the front enters to the moment the rear emerges?
    2 min.
    3 min.
    6 min.
    4min.
    5 min.
    Option B
    Total distance covered = (7/2 + 1/4) miles
    = 15/4 miles
    Time taken = (15/4*75)hrs. = 1/20 hrs.= (1/20*60)min. = 3 min.

     

  10. In how many different ways can the letters of the word ‘OPTICAL’ be arranged so that the vowels always come together?
    500
    680
    610
    720
    700
    Option D
    We have to arrange the letters PTCL (OIA).
    Now, 5 letters can be arranged in 5! = 120 ways.
    The vowels (OIA) can be arranged among themselves in 3! = 6 ways.
    Required number of ways = (120 x 6) = 720
