That knowledge is a prerequisite here.

Here, we deal with Word problems.

Word problems

Word Problems on multiplication
will be similar to the examples
1, 2, 3 and exercise 1B of
multiplication. If the numbers in the word
problems are bigger, we can
find their product using the
knowledge of
mutiplication
of higher digit numbers. The following example
will clarify the method.

Example of multiplication
Word problem

problem :
If the population of the world is
growing at the rate of 1 person
per second, find the increase in
population in one year. Give your
answer in figures and words.

Solution :
Growth of population
per second = 1

Growth of population
per minute = 1 x 60 = 60

Growth of population
per hour = 60 x 60 = 3600

Whenever there are zeros in
the multiplying numbers,
multiply the numbers without
zeros and then put the
number of zeros to the right
side of the resulting number.

So, to find 60 x 60, first find
6 x 6 which is 36.Then put
two zeros to the right of 36.

Thus 60 x 60 = 3600.

One year = 365 days
= 365 x 24 hours

Multiplication of 365
with 24 is shown below.

       365
        24
     ------           2  2
      1460        1  1
      730
     ------
      8760
     ------

Thus, Number of hours
in one year = 8760.

Growth of population
in one year
= Growth of population per hour
x Number of hours in one year
= 3600 x 8760

Here, we find 876 x 36 first.

       876
        36
     ------           3  4
      5256        1  2
     2628
     ------
     31536
     ------

So, 3600 x 8760 = 31536000

Thus, Growth of population in
one year = 31536000 persons.

in words, three crores fifteen
lakhs thirty six thousands.

or thirty one millions five
hundred thirty six thousands.
