Question 1 of 10
1. Question
1 pointsCategory: Quantitative AptitudeA and B can complete a work in 15 days and 25 days respectively. They undertook to do a job for Rs 9450. Now with the help of C they did in 7 1/7 days. What will C get as his share?
Correct
Explanation:
1/15 + 1/25 + 1/x = 7/50
So x = 30 days, C can do in 30 days
So money will be shared in ratio 1/15 : 1/25 : 1/30 = 10 : 6 : 5
So C will get = 5/21 * 9450Incorrect
Explanation:
1/15 + 1/25 + 1/x = 7/50
So x = 30 days, C can do in 30 days
So money will be shared in ratio 1/15 : 1/25 : 1/30 = 10 : 6 : 5
So C will get = 5/21 * 9450 
Question 2 of 10
2. Question
1 pointsCategory: Quantitative AptitudeThere are 1000 boys and 800 girls in a school. 75% of the boys and 92% of the girls passed in an examination. What is the approximate percentage of students who did not pass that exam?
Correct
Explanation:
Boys who dint pass = (25/100)*1000 = 250
Girls who dint pass = (8/100)*800 = 64
Total who dint pass = 250+64 = 314 out of total 1000+800 = 1800 students
So required % = (314/1800)*100Incorrect
Explanation:
Boys who dint pass = (25/100)*1000 = 250
Girls who dint pass = (8/100)*800 = 64
Total who dint pass = 250+64 = 314 out of total 1000+800 = 1800 students
So required % = (314/1800)*100 
Question 3 of 10
3. Question
1 pointsCategory: Quantitative AptitudeA and B invested in a business as Rs 3000 and Rs 4500 respectively. After 4 months C joins with Rs 5100. If after a year, C gets Rs 3230 as his share of profit, what is the share of B?
Correct
Explanation:
3000*12 : 4500*12 : 5100*8
30 : 45 : 34
So 45/34 = x/3230Incorrect
Explanation:
3000*12 : 4500*12 : 5100*8
30 : 45 : 34
So 45/34 = x/3230 
Question 4 of 10
4. Question
1 pointsCategory: Quantitative AptitudeHow many 4 letter words starting with vowel can be formed by the letters of word DOWNSTREAM such that no letter repeats?
Correct
Explanation:
There are 3 vowels, so we gave 3 choices for the first letter
There are total 10 letters in DOWNSTREAM, and one of them has occupied first place, so 9 choices for second, 8 choices for third, and 7 choices for fourth
So 3*9*8*7Incorrect
Explanation:
There are 3 vowels, so we gave 3 choices for the first letter
There are total 10 letters in DOWNSTREAM, and one of them has occupied first place, so 9 choices for second, 8 choices for third, and 7 choices for fourth
So 3*9*8*7 
Question 5 of 10
5. Question
1 pointsCategory: Quantitative AptitudeA mixture contains A and B in the ratio 2 : 3. 10 litres of mixture is replaced by 8 litres of A and the new ratio becomes 10 : 11 respectively. What is the amount of A present in the original mixture?
Correct
Explanation:
A = 2x, B = 3x
After 10 litres draw out:
A = 2x – (2/5)*10 = 2x – 4 , B = 3x – (3/5)*10 = 3x – 6
After 8 l of A put back, A = (2x – 4) + 8 = 2x +4
So (2x+2)/(3x6) = 10/11
Solve, x = 13
So A = 2x = 2*13Incorrect
Explanation:
A = 2x, B = 3x
After 10 litres draw out:
A = 2x – (2/5)*10 = 2x – 4 , B = 3x – (3/5)*10 = 3x – 6
After 8 l of A put back, A = (2x – 4) + 8 = 2x +4
So (2x+2)/(3x6) = 10/11
Solve, x = 13
So A = 2x = 2*13 
Question 6 of 10
6. Question
1 pointsCategory: Quantitative AptitudeThe length and the breadth of a rectangular room are 315 cm and 225 cm. A carpet is to be placed on the floor of the room leaving 2.5 cm space from the walls. What is the cost of carpet at Rs 1200 per metre square?
Correct
Explanation:
leaving 2.5 cm space means 5 cm from length and breadth
Area of carpet = (3155)*(2255) = 68200 cm sq. = 6.82 m sq.
So cost = 6.82*1200Incorrect
Explanation:
leaving 2.5 cm space means 5 cm from length and breadth
Area of carpet = (3155)*(2255) = 68200 cm sq. = 6.82 m sq.
So cost = 6.82*1200 
Question 7 of 10
7. 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

Explanation:
The orthocenter is the point where the three altitudes of a triangle intersect. 
Question 9 of 10
9. Question
1 pointsCategory: Quantitative AptitudeIn a rhombus, if angle A = 60 degree and AB = 10 cm, then the diagonal BD is
Correct
Explanation:
Diagonals of rhombus intersect at right angle. Also the diagonals bisect the angle and themselves also. Angle A = angle C = 60 degree
So angle B = angle D = 120 degree
In rt angled ∆AOB
Angle AOB = 90
Angle OAB = 60/2 = 30 and angle ABO = 120/2 = 60
Sin 30 = perpendicular/hypotenuse = OB/AB = OB/10
So 1/2 = OB/10 , so OB = 5cm
So BD = 5*2 = 10 cmIncorrect
Explanation:
Diagonals of rhombus intersect at right angle. Also the diagonals bisect the angle and themselves also. Angle A = angle C = 60 degree
So angle B = angle D = 120 degree
In rt angled ∆AOB
Angle AOB = 90
Angle OAB = 60/2 = 30 and angle ABO = 120/2 = 60
Sin 30 = perpendicular/hypotenuse = OB/AB = OB/10
So 1/2 = OB/10 , so OB = 5cm
So BD = 5*2 = 10 cm 
Question 10 of 10
10. Question
1 pointsCategory: Quantitative AptitudeIf x^{2} + y^{2} + 1/x^{2} + 1/y^{2} = 4, then 2x^{2} + 3y^{2} equals
Correct
Explanation:
x^{2} + y^{2} + 1/x^{2} + 1/y^{2} = 4
so [x^{2} + 1/x^{2} 2] + [y^{2} + 1/y^{2} 2] = 0
(x – 1/x)^{2} + (y – 1/y)^{2} = 0
So x – 1/x)^{2} = 0,
Solve x= 1
Similarly, y = 1
So 2x^{2} + 3y^{2} = 2*1 + 3*1 = 5Incorrect
Explanation:
x^{2} + y^{2} + 1/x^{2} + 1/y^{2} = 4
so [x^{2} + 1/x^{2} 2] + [y^{2} + 1/y^{2} 2] = 0
(x – 1/x)^{2} + (y – 1/y)^{2} = 0
So x – 1/x)^{2} = 0,
Solve x= 1
Similarly, y = 1
So 2x^{2} + 3y^{2} = 2*1 + 3*1 = 5
