Answers & Solutions:
1) Answer (A)
Let us assume that present age of Ram and his father are x and y respectively. (y > x)
We know that, (x – 6)+ (y – 6) = 32
$\Rightarrow$ x + y = 44 … (1)
16 years later,
$\Rightarrow$ $\frac{y+16}{x+16} = \frac{12}{7}$
$\Rightarrow$ 7y + 112 = 12x + 192
$\Rightarrow$ 7y – 12x = 80 … (2)
Solving both the equation, we get,
12y + 7y = 44*12 + 80
y = 32 therefore x = 44 – 32 = 12 years
Hence the ration of their ages =$\frac{32}{12} = \frac{8}{3}$ (Answer :A)
2) Answer (C)
Vishak is 5 times the present age of Deepak
V = 5 (D)
After 5 years, if Vishak is 3 times the age of Deepak at that time
V + 5 = 3(D + 5)
From the above two equations,
5D + 5 = 3D + 15
D = 5 years and V will be 25 years.
3) Answer (D)
As per the order of dictionary,
= Replicate -> Repository -> Reptile -> Republic -> Reputation
$\equiv$ 45231
=> Ans – (D)
4) Answer (C)
Expression : X_ZY_X_YZY_X
The above series is a combination of terms containing 3 letters of the form ‘XYZ’ and ‘YZX’ alternatively.
= XYZ / YZX / XYZ / YZX
=> Ans – (C)
5) Answer (B)
6) Answer (D)
Let weight of S = $4x$ kg
=> T’s weight = $\frac{4x}{2}=2x$ kg
=> R’s weight = $3\times2x=6x$ kg
=> Q’s weight = $\frac{6x}{2}=3x$ kg
=> P’s weight = $2\times3x=6x$ kg
Thus, arranging in decreasing order : $P=R>S>Q>T$
$\therefore$ P or R is the heaviest.
=> Ans – (D)
7) Answer (B)
Suraj is shorter than Gopal but taller than Tarun, => Gopal > Suraj > Tarun
Shivam is shorter than Suraj but not the shortest, => Gopal > Suraj > Shivam > Tarun
Also, Rajan is the tallest. Thus the heights in decreasing order is :
Rajan > Gopal > Suraj > Shivam > Tarun
$\therefore$ Suraj is the third shortest.
=> Ans – (B)
8) Answer (B)
Hindi is just above Sanskrit and Law is between Hindi and Mathematics.
=> Law is just above Hindi and Mathematics is just above Law.
Also, The English is between Mathematics and Science, => There are 2 more books above Mathematics, hence Sanskrit book is at the end.
Thus, final arrangement is :
$\therefore$ Law book is at the fourth position from top.
=> Ans – (B)
9) Answer (B)
Let weight of Ankit = $9x$ kg
=> Deep’s weight = $\frac{1}{9}\times9x=x$ kg
=> Ram’s weight = $4\times x=4x$ kg
=> Weight of Bablu = $\frac{4x}{2}=2x$ kg
=> Arun’s weight = $\frac{4}{7}\times2x=1.14x$ kg
$\therefore$ Ankit > Ram > Bablu > Arun > Deep
Thus, Arun’s weight is more than the weight of Deep but less than the weight of Bablu.
=> Ans – (B)
10) Answer (B)
Manish’s position from left end = 23rd
Ramesh is 11 ranks to the left of Manish, => Ramesh’s position form left end = 23 – 11 = 12th
Also, Ramesh’s position from right end = 16th
=> Number of swimmers = $(12+16)-1=27$
=> Ans – (B)
11) Answer (D)
After the discount the price of book will be,
70% of 80% of 60 = 0.7 x 0.8 x 60 (or) 33.6
After the sales tax of 5% the price of book will be,
105% of 33.6 = 35.28
Hence, option D is the correct answer.
12) Answer (C)
Cost price of the book = 300
Shop keeper wants to gain 20% i.e s.p = 360
Selling price should be 360 after giving a discount of 10%,
90% of MRP = 360
MRP = 400
Hence, option C is the correct answer.
13) Answer (B)
Given equation can be written as,
$\sqrt[6]{729 / 1000000}$
$\sqrt[6]{3^{6} / 10^{6}}$
$\frac{3}{10} = 0.3$
Hence, option B is the correct answer.
14) Answer (D)
Given equation,
$\frac{112}{\sqrt{196}}\times\frac{\sqrt{576}}{12}\times\frac{\sqrt{256}}{8}$
$\frac{112}{14}\times\frac{24}{12}\times\frac{16}{8}$
$8 \times 2 \times 2 $
$32$
Hence, option D is the correct answer.
15) Answer (A)
Given A, B and C can do a piece of work in 20,24 and 30 days respectively
Let the work be completed in $x$ days
$\Rightarrow \frac{x}{20} + \frac{x – 2}{24} + \frac{x – 5}{30} = 1$
$\Rightarrow \frac{6x + 5(x -2) + 4(x – 5)}{120} = 1$
$\Rightarrow \frac{6x + 5x -10 + 4x – 20}{120} = 1$
$\Rightarrow 6x + 5x + 4x = 120 + 30$
$\Rightarrow 15x = 150 \Rightarrow x = 10$
Work done by A,
$\frac{10}{20} \times 5400 = 2700$
Hence, option A is the correct answer.
