Question 7 of 10
7. Question
1 pointsCategory: Quantitative AptitudeA hollow cylindrical tube is open at both ends is made of iron 4cm thick. If the external diameter be 52cm and the length of the tube be 120cm, find the number of cubic cm of iron in it? approx
Correct
Explanation
H = 120 external diameter – 52
External radius = 26
Internal radius = 264 =22
Volume of iron = external volume – internal volume
22/7 * 26 * 26 * 120 – 22/7 * 22 * 22 * 120 = 72411Incorrect
Explanation
H = 120 external diameter – 52
External radius = 26
Internal radius = 264 =22
Volume of iron = external volume – internal volume
22/7 * 26 * 26 * 120 – 22/7 * 22 * 22 * 120 = 72411 
Question 8 of 10
8. Question
1 pointsCategory: Quantitative AptitudeA man cover a distance in t hrs, if he met with an accident after 20km and he then run at his 3/5th of his normal speed, so he reaches his destination 40minutes late. If he met with an accident at 30km then he reaches only 30min late. Find his original speed?
Correct
Explanation
After moving 10km more, man saves 10minutes. For saving of 40minutes he has to cover 40km.
Now speed: after accident before accident
. 3 5
Time 5 3
. (+2)
2=40minutes
1=20min
(Normal time) 3= 60min
So, he covers 40km in 60min with normal speed = 40kmphIncorrect

Question 9 of 10
9. Question
1 pointsCategory: Quantitative AptitudeX, Y and Z started a business with their investments in the ratio 1:2:4. After 6 months X invested the half amount more as before and Y invested twice the amount as before while Z withdraw 1/4th of their investments. Find the ratio of their profits at the end of the year.
Correct
Explanation
Let us assume their initial investments were x, 2x and 4x respectively.
Therefore, ratio of their investments during the whole year
= [(x * 6) + (3x/2 * 6)]: [(2x * 6) + (4x * 6)]: [(4x * 6) + (3x * 6)]
= 15x: 36x: 42x
= 5 :12 :14Incorrect

Therefore, ratio of their investments during the whole year
= [(x * 6) + (3x/2 * 6)]: [(2x * 6) + (4x * 6)]: [(4x * 6) + (3x * 6)]
= 15x: 36x: 42x
= 5 :12 :14 
Question 10 of 10
10. Question
1 pointsCategory: Quantitative AptitudeThe difference between a twodigit number and the number obtained by interchanging two digits of the number is 9. The sum of the two digits of the number is 15. What is the product of two digits of twodigit number?
Correct
Explanation
Let the digit of unit place be x.
So, the digit of tens place will be (15 ⎯x)
[10 (15 ⎯x) + x]⎯[10x + (15 ⎯x)] = 9
150 ⎯10x + x ⎯10x ⎯15 + x = 9
135 ⎯18 x = 9
18x = 126
x = 7
Thus, the digits of the number are 7 and 8.
So, the multiple of digits = 56Incorrect
