A takes 9 hrs to type 36 pages

=> A’s efficiency = $\frac{36}{9}=4$ pages/hr

Similarly, B’s efficiency = $\frac{40}{5}=8$ pages/hr

A typed first 60 pages alone, => Time taken to print 60 pages = $\frac{60}{4}=15$ hours

Similarly, time taken to print last 60 pages by A and B together = $\frac{60}{(4+8)}=5$ hours

$\therefore$ Total time taken to complete the book = $15+5=20$ hours

=> Ans – (B)

Let the ages of A, B and C respectively be $5x,8x$ and $9x$ years.

According to ques, => $5x+9x=56$

=> $x=\frac{56}{14}=4$

$\therefore$ B’s age = $8\times4=32$ years

=> Ans – (D)

Present ages of the persons are 36 and 50 years respectively.

According to ques,

=> $\frac{36+n}{50+n}=\frac{3}{4}$

=> $144+4n=150+3n$

=> $4n-3n=150-144$

=> $n=6$

=> Ans – (D)

Let present age of husband, wife and child be $h,w,c$ years respectively.

Average age of husband, wife and their child 3 years ago = 27 years

=> Total present ages of husband, wife and their child = $(27+3)\times3$

=> $h+w+c=90$ ———(i)

Similarly, present age of wife and the child = $(20+5)\times2$

=> $w+c=50$

Subtracting equation (ii) from (i), we get :

=> $h=90-50=40$

$\therefore$ The present age of the husband = 40 years

=> Ans – (B)

Let present age of A = $5x$ years and B = $6x$ years

According to ques,

=> $\frac{5x+7}{6x+7}=\frac{6}{7}$

=> $35x+49=36x+42$

=> $36x-35x=49-42$

=> $x=7$

$\therefore$ Present age of A = $5\times7=35$ years

=> Ans – (A)

let surya’s age=s
ravi’s age=r
Given s-r=12
r=0.4(r+s)
0.6r=0.4s
0.6(s-12)=0.4s
0.6s-7.2=0.4s
0.2s=7.2
s=36 yers
9 years from now age will be 36+9=45 years

Assuming, present age of Rahul= x years  and his sister= y years.

So, Present ratio= $x\div y= 3\div4$     …..(i)

Before 10 years the ratio of their ages

=$(x-10)\div (y-10)= 13\div19$           ……(ii)

Solving equation (i) & (ii),

We get, x=36 years and y=48 years.

Therefore, Option A is correct.

Ratio of parents present age is 11:10 And the ratio of ages of the father and mother will be 19:18 when the son will be twice his present age

Let the present age of son be x

Then the twice age will be 2x

According to question:

$\frac{11 + 2x}{10 + 2x} = \frac{19}{18}$

$18(11 + 2x) = 19(10 + 2x)$

$198 + 36x = 190 + 38x$

$8 = 2x$

$x = 4$

Ratio of present ages will be:

$\frac{11 + x}{10 + x} = \frac{11 + 4}{10 + 4}$

Required ratio is: (15/14).

A is correct choice.

Let say, Simi and Seema’s present age is 5k and 4k.

So, (5k+9)/(4k+9)=8/7 .

or, 35k+63=32k+72 .

or, 3k=9.

or, k=3 .

Simi’s present age=5×3=15.

B is correct choice.

Five years ago, the ratio of the ages of a father and his son was 5 : 3.

As we know that when time progresses the ratio between the ages always decreases.

$Ratio of age_{5 years ago} > Ratio of Present age > Ratio of age_{5 years later}$

Option D violates this. $[\frac{7}{3} > \frac{5}{3}]$

Option D is correct.

Let the present ages of Mahesh and Ajay be 3x years and 2x years respectively.
Then, Their ages after 8 years will be 3x+8 years and 2x+8 years.
Given, $\dfrac{3x+8}{2x+8} = \dfrac{11}{8}$

$24x+64 = 22x+88$
=> $2x = 24$
=> $x = 12$
Then, Present ages of Mahesh and Ajay are 36 years and 24 years respectively.
Present age of Mahesh’s son = Half of Present age of Ajay = 12 years.

Given 2 grandparents average as 65 so sum of their ages=65*2=130 years
Also given 3 parents average as 32 so sum of their ages=32*3=96 years
Also given 4 grandchildren average as 8 so sum of their ages=8*4=32 years
Total sum of ages=130+96+32=258 years
Average=258/9
=86/3 years

Let the ages of Arun and Anand be 3x and x
After 5 years Arun’s age=3x+5 and Anand’s age=x+5
Given 3x+5=2(x+5)+5
3x+5=2x+10+5
x=10
Present age of Arun=30 years

Let the present ages of Husband, Wife and Child be H, W and C years respectively.
Given, $\dfrac{H-4+W-4+C-4}{3} = 26 => H+W+C-12 = 78 => H+W+C = 90$
$\dfrac{W-3+C-3}{2} = 22 => W+C – 6 = 44 => W+C = 50$
Substituting W+C = 50 in above equation.
H+50 = 90 => H = 40
Therefore, The present age of the husband = 40 years.

Let ages of A and B 4 years age be $5x$ and $7x$ years respectively.

=> Ratio of ages 4 years from now (i.e. 8 years from then) = $\frac{5x+8}{7x+8}=\frac{7}{9}$

=> $45x+72=49x+56$

=> $4x=16$

=> $x=4$

Ratio of ages 12 years from now = $\frac{5(4)+16}{7(4)+16}=\frac{36}{44}$

= $9:11$

=> Ans – (C)

Let present ages of Meera and Sheela be $9x$ and $5x$ years respectively.

According to ques, => $9x=5x+8$

=> $9x-5x=4x=8$

=> $x=2$

$\therefore$ Present age of Sheela = $5\times2=10$ years

=> Ans – (B)

Let present age of A = $15x$ years and B = $8x$ years

According to ques,

=> $\frac{15x+8}{8x+8}=\frac{17}{10}$

=> $150x+80=136x+136$

=> $14x=136-80=56$

=> $x=\frac{56}{14}=4$

$\therefore$ Ratio of ages of A and B after 10 years from now = $\frac{15\times4+10}{8\times4+10}$

= $\frac{70}{42}=5:3$

=> Ans – (C)

Let Savan ‘ age be s and Akshan be a.

A/c to question ,

s = 4a

10 years later ,

s + 10 = 2(a + 10)

Solving these two questions , a = 5

s = 20

So , the answer would be option b)20.

Let the age of Shipra be s and Malini be m.

s + m = 65 —-(1)

After 5 years ,

s + 5 = m + 5 + 15

s – m =15—–(2)

Solving (1) and (2) , we get ,

s = 40 and m = 25

So , the answer would be option a)25 years.

Four years ago ,

$\frac{A’ age}{B’ age}$ = $\frac{4}{5}$

Suppose A’ age = 4x and B’s age= 5x

Eight years later ,

$\frac{A’ age}{B’ age}$ = $\frac{11}{13}$

$\frac{4x + 12}{5x + 12}$ = $\frac{11}{13}$

52x + 156 = 55x + 132

x = 24 / 3 = 8

Present ages of A = 4x + 4 = 36 and B = 5x + 4 = 44

Sum of their present ages = 80

So , the answer would be option a)80.
