Easy trick ~😐 n(A-B)= n(only A) =>n(AuB) = n(only A)+n(B) => 326+47= 373😮‍💨

[@alishashaikh9996]

In IIT multiple questions are come if this trick will apply in another question if the question will right then may be your assumption is correct .... I also apply this trick ... Dude

[@kevin_vr17]

but what if there are some n(only A) elements in n(B)? we must do n(A) intersection with n(B) [which is n(A) - n(only A)] so then we can get the number of elements that both n(A) and n(B) have in common. then just add n(A) + n(B) and subtract with the intersect to get the union n(A) U n(B)

[@hardilsawaiyan9142]

[@kanchanranjitkar1983]

(A-B) = N only (A) so, the n(A intersection B) = n(A) -n only (A) = 115 - 47 = 68. and n(AUB) = n(A) + n(B) -n(A intersection B) = 115 + 326 - 68 = 373.

[@Libex355]

Doesn't even have to do this much n(A-B) + n(B) = n (A U B) 47 + 326 = 373 Easyyyyy

[@SHUBAM-_-]

@Libex355 I wad about to comment that because A-B is already given so we just have to add the elements of B to it , as simple as that 😁😁

[@adilakshmiadithyanmremesh799]

Yes I also thought it so

[@Leonalbenz66]

Simply done by properties of intersection n(A n B) = n(A) + n(A-B) From this we get the value of n(AnB) And put this value in two cardinal no formula - - : n(A U B) :: n(a) +n(b) - n(AnB)

Bro it so simple n(A-B)+n(B) we can find using vendigram so 326+47=373 Commen logic

[@Ganesh-13056]

IIT dholakpur question

[@Gamingxone.]

Aagya samjh .., weldone mam ❤❤❤

[@imVkohliii]

We use the formula for the union of two sets: n(A \cup B) = n(A) + n(B) - n(A \cap B) Here, we are given: n(A - B) = n(A) - n(A \cap B) From this, we find: n(A \cap B) = n(A) - n(A - B) = 115 - 47 = 68 Now substitute into the formula for : n(A \cup B) = 115 + 326 - 68 = 373 Thus, .

[@Ere79769]

Is easy n(Union) = n(A) +n(B) -n (A intersection B ) Answer is 373 eaay

[@suraJ8723]

A is correct simple question 😊

[@MRRAHMAN-cy8cz]

[@AyuushmaanMalik]

oh my goddd itna mushkil ☕☕

[@aamiriqbal7035]

[@Aryanphirkeu]

😂😂😂 beta ye tatti hai jee advanced ke samne

[@harshretro414]

not even jee mains level

[@iit7886]

i think the coreect ans is 230 its simply A U B means - n(A) + n(B) - n(A INTERSECTION B) = 326 + 47-211 = 441-211=230 [ according to venn diagram ]

[@suraJ8723]

No. Of elements in B is 326 how u write 47

[@justarandomguy3759]

n(A-B) can be seen as all terms of B common with A removed from A. If you add B again to it then you will have common terms as well as only B terms. So summing up n(B) & n(A-B) gives the right answer 373.

[@tanmaygoswami5260]

She's reading it as n into (A-B )😂......but her eyes are beautiful ❤️

[@HiteshGarjola]

Answer -394 hai

[@mridultiwari9515]

Mujhe bhi wahi laga tha 😢

[@HiteshGarjola]

🙃acha

[@gauthamanand2279]

Thats (A-B)not (A intersection B) So 115-47=68=A intersection B n(A)+n(B)-n(A intersection B)= 115+326-68=373 I think now you understood this😊😊😊

[@nashwasak1515]

Is that Roma Asrani????

[@10minutesmathexplorer69]

I think The explanation is too procedural, imagine the venn's diagram, A-B contains element of A which not intersect with B, so if we combine it with B, we'll get the union of A and B. Mathematically, n(A-B) + n(B) = n(A U B)

I can do it directly by n(B) + n(A-B) 326+47 373😅😅

[@pug-lifeapocalypse2653]

Like, how ? (I am a 9th grader so please explain these stuffs to me)

[@X0U8-]

​​@@pug-lifeapocalypse2653 OK, (A-B) contains all elements of A except those are present in B . Ig. If A ={5,6,7,8} and B = {1,2,5,6} and (A-B) = ={7,8} Now here you can see that if we want all elements of A and B ie. ( A U B ) then here we have to add all elements of B . Ig. (A-B) U B = {1,2,5,6,7,8} That's it

Ya so calculate it then...n(AintersectionB)=68 so n(AunionB)=n(A)+n(B)-n(AintersectionB)= 115+326-68=373
