SOLUTIONS:

1.
From the bar graph,
No. of years before A married = 6
Let the age of A at the time of his marriage
be x years.
So, the present age of A = (x + 6) years.
The present age of A is (5/4) times his age
at the time of his marriage.
So, we can write now,
(x + 6) = (5/4) × x
⇒ 4x + 24 = 5x
⇒ x = 24
So, the present age of A = (24 + 6) years =
30 years.
His brother was 10 years younger than him
at time of his marriage.
∴ The present age of his brother = 30 – 10
= 20 years.

2.
From the bar graph,
No. of years before F married = 5
Let the age of F at time of his marriage be x
years.
F’s wife is 4 years younger than him.
So, the age of his wife at time of their
marriage = (x – 4) years.
8 years from now, the sum of their ages will be 86 years.
So, we can write now,
(x + 5 + 8) + [(x – 4) + 5 + 8] = 86
⇒ x + 13 + x + 9 = 86
⇒ 2x = 64
⇒ x = 32
So, the age of his wife at the time of their
marriage = 32 – 4 = 28 years.
∴ The present age of his wife = 28 + 5 = 33
years.

3.
From the bar graph,
No. of years before D married = 8
6 years from now, the age of D will be 40
years.
So, the present age of D = 40 – 6 = 34
years
And, the age of D at the time of his
marriage = 34 – 8 = 26 years.
The second child of F was born after 6
years of marriage.
So, the age of D when his second child
was born = 26 + 6 = 32 years.
Then, the present age of the second child
= 34 – 32 = 2 years.
The first child is 4 years older than second
one.
So, the present age of first child = 2 + 4 =
6 years.
∴ 6 years from now, the sum of the two
children = (6 + 6) + (2 + 6) = 20 years.

4.
Let present age of B & E be B & E yrs
respectively.
(B-4)/(E-3) = 10/9 ⇒ (B-4)/(B-7) = 10/9 ⇒
B= 34 ⇒ E = 30
So, Reqd. Ratio = 17:15

5.
From the bar graph,
No. of years before F married = 5
We can find from the graph that C was
also married 5 years ago. That means C
and F are married in the same year.
Let C is x years younger than F.
So, the present age of C = (35 – x) years.
The ratio of their ages at the time of
marriage was 6 : 5.
So, we can write now,
35-5/35-x-5 = 6/5
⇒ 150 = 180 – 6x
⇒ 6x = 30
⇒ x = 5
So, the present age of C =35 – 5 = 30
years.
Then, the age of F, 5 years before
marriage = 35 – 5 – 5 = 25
And, the age of C, 5 years before marriage
= 30 – 5 – 5 = 20
∴ The required sum = 25 + 20 = 45 years.

6.
Total number of books in 2017 = 25 + 400
+ 200 + 135 + 175 + 75 + 25 = 1035
Total number of books in 2018 = 75 + 375
+ 240 + 300 + 470 + 530 + 65 = 2055
∴Reqd. difference = 2055 – 1035 = 1020

7.
Required Ratio = 105 : 1000 = 21 : 200

8.
Reqd. % =140/200*100=70%

9.
We can clearly observe from the table that
in two Years; 2014 and 2018 have the
largest number of purchased of books and
on further comparison of data we find that
it is the Year of 2014 in which the
maximum number of books was bought.

10.
Once again we can find the answer just by
observation of data.
If we observe we find that the two price
ranges Rs. 4000 - Rs. 5000 and Rs. 500 -
Rs. 999 have the largest number of books
and on further observation we get to know
that it is Rs 4000 - Rs 5000 price range for
which the maximum number of books was
bought.
