Question:

Q.22 In a garden there are 403354 plants in  329 rows. If each row has the same number  of plants then  how many plants are there  in 115 rows?​

Solution:

There are total 403354 plants in 329 rows.

Let's find out how much number of plants are in each row.

Number of plants in each row = Total number of plants/Number of Rows

                                                  = 403354/329

                                                  = 1226

There are 1226 plants in each row.

Let's find out how much number of plants will be there in 115 rows.

Number of plants in 115 rows =>

Number of Rows * Number of plants in each row

115 * 1226

140990

   

There will be 140990 plants in 115 rows.                                              

Answer 2

GIVEN :

• Number of plants in a garden in 329 rows = 403354
• each row has the same number of plants .

TO FIND :

The number of plants are there in 115 rows.

SOLUTION :

To find the number of plants are there in 115 rows , we will first find the number of plants in one row.

It is given that =>

⟹$Number \: of \: plants \: in \: 329 rows = 403354$

⟹$Number \: of \: plants \: in \: 1 row = \frac{403354}{329}$

⟹$Number \: of \: plants \: in \: 1 row = 1226$

------------------------

⟹Now to find - the number of plants in 115 rows , we will find the product of Number plants in 1 row and number of rows (115)

the number of plants in 115 rows ⟹

⟹(Number plants in 1 row )× (115)

⟹$1226 \times 115$

⟹$140990$

ANSWER :

⟹ number of plants in 115 rows = 140990
