Question 11 of 20
11. Question
A starts a business with a capital of Rs. 1500. B joins the business 6 months after the start of the business and C joins the business after 8 months. At the end of the year their respective shares in the profit was in ratio off 5:3:3. What is the sum of amount put in the business by B and C together?
Correct
Answer a
The share of A, B and C = [1500*12]: 6B: 4C = 5: 3: 3
5’s = 1500*12 = 18000
1’s = 18000/5 = 3600
Capital of B = 3600*(3/6) = Rs. 1800
Capital of C = 3600*(3/4) = Rs. 2700
Total Money invested= 1800 + 2700 = Rs. 4500
Incorrect
Answer a
The share of A, B and C = [1500*12]: 6B: 4C = 5: 3: 3
5’s = 1500*12 = 18000
1’s = 18000/5 = 3600
Capital of B = 3600*(3/6) = Rs. 1800
Capital of C = 3600*(3/4) = Rs. 2700
Total Money invested= 1800 + 2700 = Rs. 4500
Question 12 of 20
12. Question
Two Stations A and B are 462 km apart. A train leaves from station A to station B and at the same time another train leaves station B to A. Both the trains meet 5.5 hours after they start moving. If the train that starts from station A is 28 km/hr faster than the other one, what is the ratio of the speeds of both the trains?
Correct
Answer c
Let the speed of the first train be x and that of the second train be y
Then, x-y= 28…… (i)
Time = Distance/Speed
5.5 = 462/(x + y)
x + y = 462/5.5
x + y = 84…… (ii)
By solving,
2x= 112
x= 56, y= 28
Ratio of their speed= 56: 28= 2 : 1
Incorrect

13. Question
The circumference of a circle is equal to the perimeter of a square whose area is 1089 sq cm. What is the area of the circle?
Correct
Answer a
The circumference of a circle = Perimeter of a Square
Area of Square = a^{2} = 1089
Side (a) = 33 cm
Perimeter of square = 4a = 33*4 = 132 cm
According to the question,
2πr = 132
2*(22/7)*r = 132
r = 21
Area of the circle= πr^{2} = (22/7)*21*21 = 1386 Sq cm
Incorrect
Answer a
The circumference of a circle = Perimeter of a Square
Area of Square = a^{2} = 1089
Side (a) = 33 cm
Perimeter of square = 4a = 33*4 = 132 cm
According to the question,
2πr = 132
2*(22/7)*r = 132
r = 21
Area of the circle= πr^{2} = (22/7)*21*21 = 1386 Sq cm
Question 14 of 20
14. Question
A shopkeeper sold an article at 12% discount on marked price yet he gains 25%. If the marked price of the article is Rs.2500, then the marked price of the article is approximately what percent more than the cost price?
Correct
Answer a
MP*(88/100) = CP*(125/100)
=> 2500 *88 = CP*125
=> CP = (2500*88)/125
=> CP = Rs. 1760
Required percentage = [(2500 – 1760)/1760] x 100
= > (740/1760) x 100 = 42.04% = 42 %
Incorrect
Answer a
MP*(88/100) = CP*(125/100)
=> 2500 *88 = CP*125
=> CP = (2500*88)/125
=> CP = Rs. 1760
Required percentage = [(2500 – 1760)/1760] x 100
= > (740/1760) x 100 = 42.04% = 42 %
Question 15 of 20
15. Question
Ratio of the present ages of Rajesh and his wife is 9:8. Four years ago, ratio of their ages was 8:7. After how many years ratio of their ages will be 13:12?
Correct
Answer b
Let the present ages of Rajesh and his wife are 9x and 8x respectively.
(9x – 4)/(8x – 4) = 8/7
=> 63x – 28 = 64x – 32
=> x = 4
Present age of Rajesh = 9x = 9 * 4 = 36 years
Present age of his wife = 8x = 8 * 4 = 32 years
Let after p years ratio of their ages will be 13:12
(36 + p)/(32 + p) = 13/12
=> 432 + 12p = 416 + 13p
=> p = 432 – 416
=> p = 16 years
Incorrect
Answer b
Let the present ages of Rajesh and his wife are 9x and 8x respectively.
(9x – 4)/(8x – 4) = 8/7
=> 63x – 28 = 64x – 32
=> x = 4
Present age of Rajesh = 9x = 9 * 4 = 36 years
Present age of his wife = 8x = 8 * 4 = 32 years
Let after p years ratio of their ages will be 13:12
(36 + p)/(32 + p) = 13/12
=> 432 + 12p = 416 + 13p
=> p = 432 – 416
=> p = 16 years
