11)A fisherman,s day is rated as good if he catches 9 fishes ,fair if 7 fishes and bad if 5 fishes .He catches 53 fishes in a week n had all good, fair n bad days in the week. So how many good, fair n bad days did the fisher man had in the week.
Sol:
good days means --- 9 fishes so 53/9=4(remainder=17) if u assume 5 then there is no chance for bad days.
fair days means ----- 7 fishes so remaining 17 --- 17/7=1(remainder=10) if u assume 2 then there is no chance for bad days.
bad days means -------5 fishes so remaining 10---10/5=2days.

4*9=36
7*1=7
2*5=10
36+7+10=53...
Ans: 4 good, 1 fair, 2bad. ==== total 7 days.

12) x+y+z=7--------- eq1
9*x+7*y+5*z=53 -------eq2
Sol:
Multiply eq 1 by 9,
9*x+9*y+9*z=35 -------------eq3
From eq2 and eq3
2*y+4*z=10-----eq4
Since all x, y and z are integer i should put a integer value of y such that z sud be integer in eq 4.....And there will be two value y=1 or 3 then z = 2 or 1 from eq 4
For first y=1,z=2 then from eq1 x= 4
So 9*4+1*7+2*5=53.... Satisfied
Now for second y=3 z=1 then from eq1 x=3
So 9*3+3*7+1*5=53 ......satisfied
So finally there are two solution of this question

51) The total expense of a boarding house is partly fixed and partly variable with the number of boarders. The charge is Rs.70 per head when there are 25 boarders and Rs.60 when there are 50 boarders. Find the charge per head when there are 100 boarders.
a) 65
b) 55
c) 50
d) 45
Sol: let a = fixed cost and
k = variable cost and n = number of boarders
Total cost when 25 boarders c = 25*70 = 1750 i.e. 1750 = a + 25k
Total cost when 50 boarders c = 50*60 = 3000 i.e. 3000 = a + 50k
Solving above 2 eqns, 3000-1750 = 25k i.e. 1250 = 25k i.e. k = 50
Therefore, substituting this value of k in either of above 2 eqns we get
a = 500 (a = 3000-50*50 = 500 or a = 1750 - 25*50 = 500)
So total cost when 100 boarders = c = a + 100k = 500 + 100*50 = 5500
So cost per head = 5500/100 = 55

52) Amal bought 5 pens, 7 pencils and 4 erasers. Rajan bought 6 pens, 8 erasers and 14 pencils for an amount which was half more than what Amal had paid. What % of the total amount paid by Amal was paid for pens?
a) 37.5%
b) 62.5%
c) 50%
d) None of these
Sol: Let, 5 pens + 7 pencils + 4 erasers = x rupees
So 10 pens + 14 pencils + 8 erasers = 2*x rupees
Also mentioned, 6 pens + 14 pencils + 8 erasers = 1.5*x rupees
So (10-6) = 4 pens = (2-1.5) x rupees
So 4 pens = 0.5x rupees => 8 pens = x rupees
So 5 pens = 5x/8 rupees = 5/8 of total (note x rupees is total amt paid by
Amal) i.e. 5/8 = 500/8% = 62.5%
Ans: 62.5%

53) I lost Rs.68 in two races. My second race loss is Rs.6 more than the first race. My friend lost Rs.4 more than me in the second race. What is the amount lost by my friend in the second race?

81) 2 trees are there. One grows at 3/5 of the other. In 4 years total growth of the trees is 8 ft. what growth will smaller tree have in 2 years.
Sol: THE BIG TREE GROWS 8FT IN 4 YEARS=>THE BIG TREE GROWS 4FT IN 2 YEARS.WHEN WE DIVIDE 4FT/5=.8*3=>2.4
4 (x+ (3/5) x) =88x/5=2x=5/4
After 2 years x= (3/5)*(5/4)*2 =1.5 (less than 2 feet)

82) There is a six digit code. Its first two digits, multiplied by 3 gives all ones. And the next two digits multiplied by 6 give all twos. Remaining two digits multiplied by 9 gives all threes. Then what is the code?
Sol: Assume the digit xx xx xx (six digits)
First Two digit xx * 3=111
xx =111/3=37
(First two digits of 1 is not divisible by 3 so we can use 111)
Second Two digit xx*6=222
xx=222/6=37
(First two digits of 2 is not divisible by 6 so we can use 222)
Third Two digit xx*9=333
xx=333/9=37
(First two digits of 3 is not divisible by 9 so we can use 333)

83) There are 4 balls and 4 boxes of colors yellow, pink, red and green. Red ball is in a box whose color is same as that of the ball in a yellow box. Red box has green ball. In which box you find the yellow ball?
Sol: Yellow box can have either of pink/yellow balls.
if we put a yellow ball in "yellow" box then it would imply that "yellow" is also the color of the box which has the red ball(because according 2 d question,d box of the red ball n the ball in the yellow box have same color)
Thus this possibility is ruled out...
Therefore the ball in yellow box must be pink, hence the color of box contain in red ball is also pink....
=>the box color left out is "green", which is allotted to the only box left, the one which has yellow ball.
Ans: green

84) A bag contains 20 yellow balls, 10 green balls, 5 white balls, 8 black balls, and 1 red ball. How many minimum balls one should pick out so that to make sure the he gets at least 2 balls of same color.
Sol: suppose he picks 5 balls of all different colors then when he picks up the sixth one, it must match any on of the previously drawn ball color. Thus he must pick 6 balls
Ans: he should pick 6 balls totally.

85) WHAT IS THE NUMBER OF ZEROS AT THE END OF THE PRODUCT OF THE NUMBERS FROM 1 TO 100?
Sol: For every 5 in unit place one zero is added
so between 1 to 100 there are 10 nos like 5,15,25,..,95 which has 5 in unit place.
Similarly for every no divisible by 10 one zero is added in the answer so between 1 to 100 , 11 zeros are added
For 25, 50, 75 3 extra zeros are added
So total no of zeros are 10+11+3=24

86) There are two numbers in the ratio 8:9. If the smaller of the two numbers is increased by 12 and the larger number is reduced by 19 thee the ratio of the two numbers is 5:9.
Find the larger number?
Sol: 8x: 9x initially
8x+ 12: 9x - 19 = 5x: 9x
8x+12 = 5x
-> x = 4
9x = 36 (NOT SURE ABOUT THE ANSWER)

A-c = 8 so sum of diff = 8+3+5 = 16 kgs

88) A and B are shooters and having their exam. A and B fall short of 10 and 2 shots respectively to the qualifying mark. If each of them fired at least one shot and even by adding their total score together, they fall short of the qualifying mark, what is the qualifying mark?
Sol: Because each had at least 1 shot done so 10 + 1 = 11
And 9 + 2 = 11
So the ans is 11

89) A, B, C, and D tells the following times by looking at their watches. A tells it is 3 to 12. B tells it is 3 past 12. C tells it is 12:2. D tells it is half a dozen too soon to 12. No two watches show the same time. The difference between the watches is 2,3,4,5 respectively. Whose watch shows maximum time?
Sol: A shows 11:57, B shows 12:03, C shows 12:02 and D shows 11:06 therefore,
Max time is for B

90) Falling height is proportional to square of the time. One object falls 64cm in 2sec than in 6sec from how much height the object will fall.
Sol: The falling height is proportional to the square of the time.
Now, the falling height is 64cm at 2sec
So, the proportional constant is=64/ (2*2) =16;
So, at 6sec the object fall maximum (16*6*6) cm=576cm;
Now, the object may be situated at any where.
If it is>576 only that time the object falling 576cm within 6sec .Otherwise if it is situated<576 then it fall only that height at 6sec.

a) 3rd
b) 6th
c) 9th
d) 7th
In d 1st day Anand does 1/7th of total work
Similarly,
Bithu does 1/8th work in d 2nd day
Hence at the end of 3 days, work done = 1/7+1/8+1/6=73/168
Remaining work = (168-73)/168 = 95/168
Again after 6 days of work, remaining work is = (95-73)/168 = 22/168
And hence Anand completes the work on 7th day.
Ans is d) 7th day
