    9 × 2 – 2 × 5 = 18 – 10 = 8
    8 × 3 – 3 × 4 = 24 – 12 = 12
    12 × 4 – 4 × 3 = 48 – 12 = 36

  6. The simple interest on a certain sum of money for 2 yr at 8% per annum is 30 less than the simple interest on the same sum for 3 yr at 6% per annum. Find the sum in Rs.
    1500
    1000
    1120
    1450
    1223
    Option A
    T1 = 2
    R1 = 8%
    T2 = 3 yr and R2 = 6%
    Let the sum be P. Then, P × 6 × 3/ 100 − P × 8 ×2/ 100 = 30
    => 18P/ 100 – 16P/ 100 = 30
    P = Rs. 1500

     

  7. While selling a watch, a shopkeeper gives a discount of 5%. If he gives a discount of 6% he earns Rs. 15 less as profit. What is the marked price of watch ?
    Rs. 1700
    Rs. 1000
    Rs. 1300
    Rs. 1500
    Rs. 1100
    Option D
    Let the marked price be Rs.x

    = Rs. 1500

     

  8. A train 108 metre long is moving at a speed of 50 km/hr. It crosses a train 112 metre long coming from opposite direction in 66 seconds. What is the speed of the second train?
    70
    77
    86
    82
    72
    Option D
    Distance covered = (108+112) = 220 metre
    Time = 6 seconds
    Relative speed = 220/6 = 110/3 m/s
    = 110/3 × 18/5 = 132 km/hr.
    Speed of second train = (132−50) = 82 km/hr

     

  9. A complete 4/5 part of a work in 20 days. Then he completes the rest work with B in 3 days. How much time will B take alone to complete this work ?
    30(1/3) days
    37(1/2) days
    33(1/7) days
    40(1/2) days
    31(1/3) days
    Option B
    Days taken by A to complete the work
    = 20 * 5/4 = 25 days
    Work finished in 3 days
    = 3/25 + 3/x = 1/5
    => x = 37(1/2) days

     

  10. One 5 letter word is to be formed taking all letters – S, A, P, T and E. What is the probability that this the word formed will contain all vowels together?
    5/7
    8/15

    2/5
    3/8
    Option D
    Total words that can be formed is 5! = 120
    Take: S, P, T and AE So their arrangement = 4! * 2! = 48
    Required probability = 48/120 = 2/5
