Question

Raman had 30 flowers he offered some flowers in a temple and found that the ratio of the number is remaining flower to that are flowers in the beginning is 2: 5 find the number of the following offered by him in the temple .

Answer 1

Let the flower he offered In Temple is x.

So the remaining flowers are (30 - x)

Now ratio of flowers in beginning and left after offered in temple is.

(30 - x) / 30 = 2 / 5

5(30 - x) = 30*2

150 - 5x = 60

150 - 60 = 5x

5x = 90

x = 90 / 5 = 18

So the no. Of flowers offered in temple is 18.


Thanks

Answer 2

TOTAL NUMBER OF FLOWER = 30

number of flower offered in temple = x

number of flower offered remain = 30- x

so

RATIO


$\frac{remaning\: flower}{starting \: number\: flower}$



=
$\frac{30 - x}{30} = \frac{2}{5}$
=

$5(30 - x)= 60$


=
$150 - 5x = 60$

=
$90 = 5x$
=

$x = 18$




SO NUMBER OF FLOWER OFFERED IN
TEMPLE
= 1 8
