1 pointsCategory: Quantitative AptitudeArun’s present age is three times his daughter’s present age and two fifth of his father’s present age. The average of the present age of all of them is 46 years.
Quantity I: The difference between Arun’s daughter’s present age and Arun’s father’s present age.
Quantity I: After 15 years, the sum of the Arun’s daughter’s age and Arun’s age.Correct
Answer – 5. Quantity I = Quantity II or relation cannot be established
Explanation:
Let Arun’s present age = x
Then, his daughter’s age = x/3
Father’s age = (5/2)x
x + x/3 + (5/2)x / 3 = 46
x = 36 years
The required difference = 5/2*36 − 36/3 = 78 years
The required sum – [36 + 15 + 12 + 15] = 78 yearsIncorrect
Answer – 5. Quantity I = Quantity II or relation cannot be established
Explanation:
Let Arun’s present age = x
Then, his daughter’s age = x/3
Father’s age = (5/2)x
x + x/3 + (5/2)x / 3 = 46
x = 36 years
The required difference = 5/2*36 − 36/3 = 78 years
The required sum – [36 + 15 + 12 + 15] = 78 years

1 pointsCategory: Quantitative AptitudeOne year ago the ratio between Merlin’s and Shyam’s salary was 3 : 4. The ratios of their individual salaries between last year’s and this year’s salaries are 4 : 5 and 2 : 3 respectively. At present the total of their salary is Rs. 4160.
Quantity I : The salary of Merlin
Quantity II : The salary of ShyamCorrect

M1/M2 = 4/5 …..(2)
S1/S2 = 2/3 …..(3)
and M2 + S2 = 4160 …..(4)
Solving all these equations, we get M2 = Rs. 1600.Incorrect

and M2 + S2 = 4160 …..(4)
Solving all these equations, we get M2 = Rs. 1600. 
Question 5 of 10
5. Question
1 pointsCategory: Quantitative AptitudeIn a box, there are 9 blue, 6 white and some black pens. A pen is randomly selected and the probability that the pen is black is ¼.
Quantity I : Number of black Pens + 1
Quantity II : Blue Pens, White PensCorrect
Answer – 4. Quantity I ≤ Quantity II
Explanation:
Total probability = 1
Given probability of black pens = 1/4
=> Probability of blue and white pens = 1 – 1/4 = 3/4
But, given blue + white pens = 9 + 6 = 15
Hence,
3/4 —– 15
1 —– ?
=> 15 x 4/3 = 20.
Hence, total number of pens in the box = 20.Incorrect
Answer – 4. Quantity I ≤ Quantity II

Total probability = 1
Given probability of black pens = 1/4
=> Probability of blue and white pens = 1 – 1/4 = 3/4
But, given blue + white pens = 9 + 6 = 15
Hence,
3/4 —– 15
1 —– ?
=> 15 x 4/3 = 20.
Hence, total number of pens in the box = 20.
