3) In a certain year, the number of girls who graduated from City High School was twice the number of boys. If 3/4 of the girls and 5/6 of the boys went to college immediately after graduation, what fraction of the graduates that year went to college immediately after graduation?
Answer
Assume that number of boys graduated from City H igh School = B Therefor e, number of gir ls graduated fr om City H igh School = 2* B
I t is given that 3/4 of the gir ls and 5/6 of the boys went to coll ege immediately after graduation.
H ence, total students went to coll ege
= (3/4)(2* B) + (5/6)(B)
= B * (3/2 + 5/6)
F r action of the graduates that year went to coll ege immediately after gr aduation
= [(7/3)B] / [3* B]
= 7/9
Th erefor e, the answer is 7/9

The perimeter of a square and a rectangle is the same. If the rectangle is 12 cms. by 10 cms., then by what percentage is the area of the square more than that of the rectangle?
a) 1 b) 3 c) 5/6 d) 1/2 Answer : c) 5/6 Reason :
Given that Perimeters of square and rectangle are the same.
Perimeter of rectangle of size 12 cms and 10 cms is 2(Length + Breadth) = 2(12+10) = 44 Perimeter of square = 44. (4 x side of square)
Length of each side of the square = 44/4 =11
Area of the square = Side2 = 11 x 11 = 121 sq. meter
Area of the rectangle = Length X Breadth = 12 x 10 = 120 sq. meter
Percentage Increase of area of the square to that of the rectangle = (Area of Square - Area of Rectangle) / Area of Rectangle X 100 % = (121 - 120)/120 X 100 % = 5/6 %
Question 175
Capacity of a cylindrical vessel is 25,872 litres. If the height of the cylinder is 200% more than the radius of its base, what is the area of the base in square cms?
a) 336 b) 1232 c) 616 d) cannot be determined Answer : c)616
Reason :
Let the radius be R and height be H
Height is 200% more than its radius.
This means H = R + 200% R = R (1 + 200/100) = 3 R Volume of the cylinder (formula) = π R 2H
It has been mentioned that volume of the cylinder is 25,872 cm3 22/7 R 2H = 25,872 cm3
Substituting H = 3R we get R = 14 cm
Area of the base = πR 2 = 22/7 x 142 = 616 cm2 Question 176
If the radius of a circle is increased by 12%, then the area of the circle a) decreases by 25.44%
b) increases by 25.44%
c) no change in area d) decreases by 12%
Answer : b) increases by 25.44%
Reason :
Area of circle πr 2 where r is the radius
Assume initially the radius was 10. Then area becomes 22/7x10x10 = 314.28 --> eq 1 Now if the radius is increased by 12%, it will become 10+(12/100)10 = 10+1.2=11.2 New area = 22/7 x 11.2x 11.2 = 394.24 --> eq 2
Increase in area in our case = eq 2 - eq 1 = 79.96
Percentage increase in area when radius is increased by 12% = Increase in Area / Original Area X 100% = 79.96 / 314.28 X 100 =25.44%

a) son b) son-in-law c) grandson d)nephew Answer : c) grandson
Man’s son’s sister = Man’s daughter. Man’s daughter is the mother of Lakshmi’s husband.
Question 180
A cylinder of diameter 14 and height 7 is converted into a cone of radius 6. Now, what could be the percentage height of the new shape ?
a. 308% b. 32% c. 2150% d. 215%
Answer: a. 308%
Reason:
Volume of cylinder = pi X r 2X h = pi X 49 X 7 = 343pi Volume of the cone = Volume of cylinder = 343pi -> eq 1
Volume of cone is given by formula = 1/3 (pi X r 2 X h) = 36/3(pi)(h) = 12(pi)(h)--> eq 2 (here h is the height of the cone)
From eq 1 and eq 2 we get 343pi = 12(pi)(h) Therefore, height of the cone = 343/12
Percentage increase in height = ((height of the cone - height of the cylinder )/ height of the cylinder) X 100%
= (343/12 - 7)/7 X 100
= 259/84 X 100
= 308% approximately.
Question 181
Find the largest number which gives out reminders 2 and 5 when used to divide 80 and 122.
a. 19 b. 17 c. 13 d. infinite number of solutions Answer: c. 13.
Reason:
This is a very simple question where finding out the HCF of 80 - 2 and 122 - 5 will give the answer.
The HCF of 78 and 117 is 13
Hint : In case you are confused about HCF, LCM stuff, you can very well do a trial and error with options which is not a difficult task but could consume a little more time than the direct method.
Question 182
Find the ratio of the volumes of a sphere and cone of same radius. Also the height of the cone is twice its radius.
a. 3 : 1 b. 4 : 3 c. 4 : 1 d. 2 : 1 Answer : d. 2 : 1
Reason:
This is again a simple question that can be answered by knowing formulas.
Volume of a cone = 1/3 pi r 2 h where r is the radius and h is the height of the cone.
Now, h = 2r as per the question.
Hence volume of the cone = 2/3 pi r 3
Volume of a sphere = (4/3) pi r3 where r is the radius which is the same as that of the cone.
Ratio of volume of sphere to that of cone = (4/3) pi r 3 / 2/3 pi r 3 = 2 : 1 Question 183

Answer : a. 720
The given sequence is of the form n3-n where n starts from 8. Hence the blank should be filled by 93-9 which is 720.
Question 184
Consider a group of working men. If 1/10th of the workers are absent then work of each person would be increased by.
a. 20% b. 22.22% c. 10% d. 11.11%
Answer 1
Answer is d. 11.11%
Let us assume 100 units of work is divided among 10 men.
When no one is absent, each member have to do 100/10 = 10 units of the work With 1/10th of men absent, there would be 9 men present.
Now, if 100 units of work is to be done by the 9 men present, each should do 100/9 units of work.
Extra work required from each member when only 9 men are present = 100/9 - 10 = 10/9 units.
Percentage of increase of work for each member = (Extra work required from each member when only 9 men are present)/ (Original amount of work when everyone is present) X 100 % = ((10/9)/10)X 100% = 11.11%
Question 185

b) Few members of team B could be over 6 feet.
Answer 2
Answer is Option b) Few members of team B could be over 6 feet.
Reason : The statement says that there is a possibility that few members of team B can actually be taller than few members of team A.
Question 186
John is supposed to walk from his house to park every morning. One morning, he is in real hurry and wants to save at least 1/3rd of the time. By how much percentage he should increase his speed.
a. 100% b. 33% c. 66% d. 50%
Answer 3
Answer is d. 50%
Let the distance between his house and park be 100 metres.
Lets assume he takes 30 mins daily. Hence his speed would be 100/30.
One day, if he wishes to save 1/3rd of 30 minutes, that is 10 minutes, he should cover the distance in 20 minutes in which case his speed would be 100/20.
Required increment in speed = 100/20 - 100/30
Required increment in speed = 100/20 - 100/30
