8874 â€“ (33)2 -5 = 7790
7790 â€“ (34)2 â€“ 5 = 6639

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 â€“ 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?
