Question 11 of 20
11. Question
5 years ago, the ratio of ages of P and Q is 5: 4. The present age of R is one-fifth of the age of P, 5 years ago. Sum of the ages of P, Q and R, after 3 years will be 89 years. Find the present age of Q?
Correct
Answer: a)
5 years ago, the ratio of ages of P and Q = 5: 4 (5x, 4x)
The present age of R = (1/5)*5x = x
Sum of the ages of P, Q and R, after 3 years = 89 years
5x + 4x + x + 10 = 89 – 9
10x = 70
X = 7
The present age of Q = 4x + 5 = 33 years
Incorrect
Answer: a)
5 years ago, the ratio of ages of P and Q = 5: 4 (5x, 4x)
The present age of R = (1/5)*5x = x
Sum of the ages of P, Q and R, after 3 years = 89 years
5x + 4x + x + 10 = 89 – 9
10x = 70
X = 7
The present age of Q = 4x + 5 = 33 years
Question 12 of 20
12. Question
The volume of cylinder 1 and 2 is in the ratio of 3: 4 and the radius of cylinder 1 and 2 is in the ratio of 5: 6. Find the ratio between the heights of cylinder 1 to that of cylinder 2?
Correct
Answer: d)
Volume of the cylinder = πr^{2}h
The ratio of volume of cylinder 1 and 2 = 3: 4
The ratio of radius of cylinder 1 and 2 = 5: 6
The ratio between the heights of cylinder 1 to that of cylinder 2
= > [π*(25)*h1]/[ π*(36)*h2] = (3/4)
= > h1/h2 = (27/25)
= > h1 : h2 = 27 : 25
Incorrect
Answer: d)
Volume of the cylinder = πr^{2}h
The ratio of volume of cylinder 1 and 2 = 3: 4
The ratio of radius of cylinder 1 and 2 = 5: 6
The ratio between the heights of cylinder 1 to that of cylinder 2
= > [π*(25)*h1]/[ π*(36)*h2] = (3/4)
= > h1/h2 = (27/25)
= > h1 : h2 = 27 : 25
Question 13 of 20
13. Question
A and B started a business by investing Rs. 30000 and Rs. 45000 respectively. After 5 months, A invested 30 % of initial investment more and at the same time C entered into a partnership by investing Rs. 50000. Find the share of B, if the total profit at the end of the year is Rs. 144430?
150 m long train crosses another train of length 200 m in 9 sec, running in opposite direction. If the speed of the first train is 65 km/hr, then find the speed of the second train (in km/hr)?
Correct
Answer: a)
T = D/S
According to the question,
9 = (150 + 200) / [(65 + x)*(5/18)]
9* [(65 + x)*(5/18)] = 350
[(65 + x)*(5/18)] = 350/9
(65 + x) = (350/9)*(18/5)
65 + x = 140
X = 75 km/hr
Incorrect
Answer: a)
T = D/S
According to the question,
9 = (150 + 200) / [(65 + x)*(5/18)]
9* [(65 + x)*(5/18)] = 350
[(65 + x)*(5/18)] = 350/9
(65 + x) = (350/9)*(18/5)
65 + x = 140
X = 75 km/hr
Question 15 of 20
15. Question
A man covered one-fourth of the distance by bus with a speed of 40 km/hr and the remaining distance will be covered by bike with a speed of 60 km/hr. Find the total distance covered by the man, if the total time taken by him is 5 hours 15 mins?
Correct
Answer: c)
Total time taken by him = 5 hours 15 min = 5 15/60 = 5 1/4 hours
T = D/S
(x/4)/40 + (3x/4)/60 = 5 1/4
x/40 + 3x/60 = (21/4)*4
(3x + 6x)/120 = 21
9x = 21*120
X = (21*120)/9
X = 280 km
Incorrect
Answer: c)
Total time taken by him = 5 hours 15 min = 5 15/60 = 5 1/4 hours
T = D/S
(x/4)/40 + (3x/4)/60 = 5 1/4
x/40 + 3x/60 = (21/4)*4
(3x + 6x)/120 = 21
9x = 21*120
X = (21*120)/9
X = 280 km

16. Question
Directions (16 – 20): Study the following information carefully and answer the given questions:
Following pie chart shows the percentage distribution of books bought by the peoples in 5 different stores in December 2017. Some males and females bought those books.
If the number of males who bought the books in Store T is 34 more than the number of females who bought the books in Store T, then find the total number of females who bought the books in store T?
Correct
Answer: a)
Let the number of males and females who bought the books be x and y respectively,
Total number of peoples bought the books in Store T = 1200*(21/100) = 252
X + y = 252 –à (1)
X – y = 34 –à (2)
By solving the equation (1) and (2), we get,
X = 143, y = 109
The total number of females who bought the books in store T = 109

If the total number of peoples bought the books from shop A is 20 % more than the total number of peoples bought the books from shop S, then find the total number of peoples bought the books from shop A and Q together?
Correct
Answer: c)
The total number of peoples bought the books from shop A
= > 1200*(15/100)*(120/100) = 216
The total number of peoples bought the books from shop Q
= > 1200*(22/100) = 264
The total number of peoples bought the books from shop A and Q together
= > 216 + 264 = 480

Answer: c)
The total number of peoples bought the books from shop A
= > 1200*(15/100)*(120/100) = 216
The total number of peoples bought the books from shop Q
= > 1200*(22/100) = 264
The total number of peoples bought the books from shop A and Q together
= > 216 + 264 = 480

The total number of peoples bought books in store P and S together in the month of Feb 2018
= > 1500*(33/100) = 495
Incorrect
Answer: d)
In the month of Feb 2018, the total number of peoples bought the books from all the given book stores
= > 1200*(125/100) = 1500
