Prev
18 is divisible by both 2 and 3. It is also divisible by 2 × 3 = 6. Similarly, a number is divisible by both 4 and 6. Can we say that the number must also be divisible by 4 × 6 = 24? If not, give an example to justify your answer.
Answer:
No, since, 12 and 36 are both divisible by 4 and 6. But 12 and 36 are not divisible by 24

"hello student
welcome back on a lead or doubt solving
session
and in today's zero doubt solving
session we are going to discuss
one more problem related to circle right
that is the circle is a part of geometry
all right okay so i'm going to read the
statement if
a x b and c by d opposite of
a circle are concurrent then find their
ratio of
av and cd right
okay that means from this given question
okay
we know that okay we have given that
the two arcs are there okay are a xp
and our cyt and both are the concurrent
right
okay that means okay our
a x b it's concurrent to
arc
c y d all right okay that is given
okay so now as we know that okay
when the two arcs are concurrent right
there cross correspondence
correspondence
okay chords are also
equal right
okay when the two arcs are
concurrent then okay their correspondent
chords will be the
equal right so from this statement we
can say that okay
okay a b is equals to
got cd all right
that means a b is equals to
c d right and that's why
a b upon c d is equals to
1 right okay we can derive this relation
right okay so in this particular case
the ratio of a b and c d will be the
one all right
that's all about today's session i hope
