    Option A
    8874, 7790, 6639, 5419, ?
    8874 – (33)2 -5 = 7790
    7790 – (34)2 – 5 = 6639
    6639 – (35)2 – 5 = 5419
    5419 – (36)2 – 5 = 4128

     

  6. Rahul purchased two cycles whose cost price was in the ratio 3:5. He sold first cycle at loss of 10% and other at profit of 15%. His overall gain was Rs.540. Find his profit percentage?
    3.512%
    5.625%
    4.125%
    6.625%
    None of these
    Option B
    15% of 5x – 10% of 3x = 540
    => x = (540*100)/(75-30) = 1200
    Required Profit % = (540*100)/(8*1200) = 5.625%

     

  7. Bowling average of a bowler was 16.8. In next match his performance was 93/5 thus his new bowling average becomes 17. Find the total runs considered by him before this match?
    589
    650
    672
    545
    700
    Option C
    Let x be the total wicket before this match.
    (16.8x + 93)/(x+5) = 17
    => x = 40
    Total runs = average * wicket
    => 16.8*40 = 672

     

  8. A shopkeeper marked an article such that he may get a profit of 25% after giving 20% discount. But the customer asked for 10% extra discount after 20%. So, that shopkeeper used a wrong weight of 900 grams instead of 1 kg. Find new profit percent of shopkeeper.
    15%
    20%
    10%
    No profit
    30%
    Option D
    CP—–SP——-MP
    80—-100—–125
    Now, 72—-90—–125
    Profit% = 18*(100/72) = 25%
    So, there is no change in profit%.

     

  9. .A boat takes 38 hours for travelling downstream from point A to point B and coming back to point C midway between A and B. If the velocity of the stream is 4 kmph and the speed of the boat in still water is 14 kmph, what is the distance between A and B?
    320
    360
    350
    333
    300
    Option B
    Speed downstream = (14+4) = 18 kmph
    Speed upstream = (14-4) = 10 kmph
    Let the distance between A and B be x km
    Time taken to travel downstream from A to B + Time taken to travel upstream from B to C(mid of A and B) = 38 hours
    => x/18+(x/2)/10=38
    => x/18+x/20=38
    => 19x/180=38
    => x/180=2
    =>x=360

     

  10. A and B go for an interview and the probability of their selection is (1/3) and (1/4) respectively. Find the probability that A will get selected but B not selected?
    1/3
    1/5
    1/7
    1/4
    1/9
    Option D
    Required Probability = (1/3)*(3/4) = ¼
