What is the ratio of the number of male passengers in bus D to the number of female passengers in bus B?
Verify mobile number to view the solution
Required ratio=95:105=19:21
The number of female passengers in bus B is what percent of the number of male passengers in Bus D and E together?
Required %=105/(95 + 30) *100=84%
If in Bus C, the price per ticket for Children, Female and Male is Rs.20, Rs.60 and Rs.80 respectively, then find the total revenue collection of bus C.
Total revenue=45 * 20 + 60 * 100 + 105 * 80=Rs. 15300
What is the difference between the total number of female in all the buses together and the total number of children in all the buses together?
Difference=(80 + 105 + 100 + 45 + 60) – (60 + 70 + 45 + 40 + 30)
=390 – 245
=145
The average number of male passengers in all the buses together is approximately what percent of the total number of passengers in bus E?
Average male passengers=(60 + 125 + 105 + 95 + 30)/5=83
Required %=(83/120) * 100=69%
The following questions are accompanied by three statements I and II. You have to determine which statement is/are sufficient to answer the question.
What is the area of the square?
Statement I: The perimeter of the square is 150% of the perimeter of rectangle and the ratio of the length to breadth of the rectangle is 3:1.
Statement II: The side of the square is equal to the radius of the circle and the circumference of the circle is 88 cm.
From statement I,
Length/breadth=3/1
So, Statement I alone is not sufficient to the answer the question.
From Statement II,
2 * 22/7 * r=88
Radius of the circle=14 cm
Area of the square=14 * 14 =196
So, Statement II alone is sufficient to the answer the question.
Only II is sufficient to the answer the question.
What is the present age of Rani?
Statement I: Rani’s age is 25% of her father’s present age and the ratio of the ages of Rani to her brother is 3:4.
Statement II: If the difference between the ages of Rani’s father and her brother is 40 years.
From Statement I,
R=25/100 * F
R/B=3/4
F – B=40
So, Statement II alone is not sufficient to the answer the question.
From I and II
4R=3B
Also 4R=F
Then, 3B=F
2B=40
B=20 years
Thus, R=15 years
Both I and II are necessary to the answer the question.
A, B and C started the business. What is the profit share of B?
Statement I:A and B started the business with investment of Rs.3000 and Rs.5000 respectively and after 4 months C joined with them.
Statement II: C’s investment is 125% of B’s initial investment. A, B and C invests their amount for 12 months, 8 months and 8 months respectively.
Investment of A=Rs. 3000
Investment of B=Rs. 5000
From statement II,
Periods of investments of A, B and C is 12 months, 8 months and 8 months.
In how many days A and C together can complete the work?
Statement I: A can complete the work in 12 days and C is 50% more efficient than B.
Statement II: A and B together can complete the work in 8 days.
A=1/12
A + B=1/8
From Statement I and II,
B=1/8 – 1/12=(3 – 2)/24=1/24
C complete the work alone=24 * 50/100=12 days
A + C=1/12 + 1/12=1/6
So, Statement I and II are necessary to answer the question.
What is the total quantity of the milk and water in the initial mixture?
Statement I: The ratio of the milk and water is 5:4. If 2 liters of water added to the mixture the ratio becomes 10:9.
Statement II: A milkman has the mixture of milk and water in the ratio of 3:2 and he sells the 20 liter of mixture to his customer.
5x/(4x + 2)=10/9
40x + 20=45x
5x=20
x=4
Total quantity =9 * 4=36 liter
So, Statement I alone is sufficient to the answer the question.
Milk/water=3/2
Only I issufficient to the answer the question.
