25kg : 20g = 50kg : 40g

Answer:

True.

We know that, 1 kg = 1000 g

So, 25 × 1000 = 25000 g

50 × 1000 = 50000g

Then, 25000g : 20g = 50000g : 40g

25000/20 = 50000/40

2500/2 = 5000/4

2500/2 is further simplified by dividing both numerator and denominator by 2 we get,

= 1250

5000/4 is further simplified by dividing both numerator and denominator by 4 we get,

= 1250

Hence, 1250 = 1250

So, 25kg : 20g = 50kg : 40g

"hello students welcome to lido q a video
session i'm sev your math tutor
and question for today is a cuboidal
vessel is 10 meter long
and 8 meter wide how high must it be
made
to hold 380 cubic meters of a liquid
here dimension of the capital vessel is
given to you
length which is
l and it is equal to 10 meter
breadth b which is equal to 8 meter
and the volume of the vessel is given
that is 380 meter cube
let h be the height of the cuboidal
vessel which we need to find
now we already know through the volume
of the cuboidal vessel we have one
formula
that is length into breath into height
so volume
and that is equal to already given to us
one volume
that is 380 meter cube
so let us equate this 380 meter cube
with length into breath into h
so 380 will be equal to
length is 10 breath is 8
and h we need to find so h is equal to
10 into 8
h is equal to 380 divided by 10 into 8
and this will give you after
simplification it will give you
height will be equal to 4.75 so that is
the value of
h therefore from this we can write
the height of vessel should be 4.75
meter
if you have any doubt regarding this you
can post it in our comment section
and subscribe to lido for more such
interesting q a sessions
thank you for watching
