If the monthly salary of the person is Rs 6,000, for how many items he has spent more than Rs 1,000 per month?
Correct
Explanation:
Shortcut
(x/100)*6000 = 1000, gives x = 16.67%
So the ones having more expense % than 16.67% which is A and CIncorrect
Explanation:
Shortcut
(x/100)*6000 = 1000, gives x = 16.67%
So the ones having more expense % than 16.67% which is A and C

Question 5 of 10
5. Question
1 pointsCategory: Quantitative AptitudeA and B started from a same point in same direction with their speeds being in the ratio 3 : 4. What is the time taken by B to reach their destination if A took 30 minutes more than B to reach destination?
Correct
Explanation:
Let time taken by B is t hrs, then by A is (t + 30/60) hrs
Speeds ratio = 3 : 4
Distance is same. So
3 * (t + 1/2) = 4 * t
Solve, t = 1 1/2 hrsIncorrect
Explanation:
Let time taken by B is t hrs, then by A is (t + 30/60) hrs
Speeds ratio = 3 : 4
Distance is same. So
3 * (t + 1/2) = 4 * t
Solve, t = 1 1/2 hrs 
Question 6 of 10
6. Question
1 pointsCategory: Quantitative AptitudeA certain amount invested at 5% rate of interest per annum for 4 years gave a simple interest of Rs 312. If the same amount would have been invested at 4% rate of interest per annum compounded annually, what would be the compound interest obtained after same time?
Correct
Explanation:
312 = P*5*4/100
So principal = Rs 1560
CI = 1560 [(1 +4/100)^2 – 1]
= 1560 [729/625 – 1]Incorrect
Explanation:
312 = P*5*4/100
So principal = Rs 1560
CI = 1560 [(1 +4/100)^2 – 1]
= 1560 [729/625 – 1] 
Question 7 of 10
7. Question
1 pointsCategory: Quantitative AptitudeA bag contains 3 white, 4 black and 5 green marbles. If 2 marbles are drawn at random from the bag, find the probability that both balls are different in color?
Correct
Explanation:
Case 1: 1 white+1 black
^{3}C_{1}*^{4}C_{1}/^{12}C_{2}
Case 2: 1 white+1 green
^{3}C_{1}*^{5}C_{1}/^{12}C_{2}
Case 3: 1 green+1 black
^{5}C_{1}*^{4}C_{1}/^{12}C_{2}
Add all cases
Or
find prob of both same color and subtract from 1Incorrect
Explanation:
Case 1: 1 white+1 black
^{3}C_{1}*^{4}C_{1}/^{12}C_{2}
Case 2: 1 white+1 green
^{3}C_{1}*^{5}C_{1}/^{12}C_{2}
Case 3: 1 green+1 black
^{5}C_{1}*^{4}C_{1}/^{12}C_{2}
Add all cases
Or
find prob of both same color and subtract from 1 
Question 8 of 10
8. Question
1 pointsCategory: Quantitative AptitudeA’s present age is 1/3 of B’s and B’s present age id 9/13 of C’s present age. The sum of their present ages is 125 years. What is the difference between the ages of A and C?
Correct
Explanation:
B = 9C/13 and A = 1/3(9C/13) = 3C/13
So 3C/13 + 9C/13 + C = 125
Solve, C = 65, so A = 3*65/13 = 15
So C – A = 6515Incorrect
Explanation:
B = 9C/13 and A = 1/3(9C/13) = 3C/13
So 3C/13 + 9C/13 + C = 125
Solve, C = 65, so A = 3*65/13 = 15
So C – A = 6515 
Question 9 of 10
9. Question
1 pointsCategory: Quantitative AptitudeA man standing on the top of the tower seas a boat coming towards him takes 10 minutes for the angle of depression to change from 30 degree to 60 degree. Find the time taken by the boat to reach the shore from this position.
Correct
Explanation:
AB/AD = tan 60 = √3
So AD = AB/√3
AB/(CD+AD) = tan 30 = 1/√3
So CD+AD = √3 AB
Solve both equations, CD = 2h/√3
Now 2h/√3 is covered in 10 minutes, so h/√3 in 5 minutesIncorrect
Explanation:
AB/AD = tan 60 = √3
So AD = AB/√3
AB/(CD+AD) = tan 30 = 1/√3
So CD+AD = √3 AB
Solve both equations, CD = 2h/√3
Now 2h/√3 is covered in 10 minutes, so h/√3 in 5 minutes 
Question 10 of 10
10. Question
1 pointsCategory: Quantitative AptitudeABC is a triangle with base AB. D is a point on AB such that AB = 5 and DB = 3. What is the ratio of the area of triangle ADC to the area of triangle ABC?
Correct
Explanation:
AB = 5, DB = 3
So AD = 53 = 2
Both ADC and ABC have same height and area of triangle is (1/2)*base*height
So required ratio is (1/2)*AD*h : (1/2)*AB*h
= AD : AB = 2 : 5Incorrect
Explanation:
AB = 5, DB = 3
So AD = 53 = 2
Both ADC and ABC have same height and area of triangle is (1/2)*base*height
So required ratio is (1/2)*AD*h : (1/2)*AB*h
= AD : AB = 2 : 5
