Is there any method to do this or it's plain tukka?

First is n, second is n+1, third is n+2, add them and you get 84.

integer 1 = x
integer 2 = x + 1
integer 3 = x + 2

x + (x+1) + (x+2) = 84

I know that. When they said consecutive it has to be like that but it's like more of a guess what numbers to use.

Vector Notes? Anyone! ?????

3 CONSECUTIVE
1: n
2: n+1
3: n+2

n+n+1+n+2=84. solve it.Nothing in maths is pure tukka

I know that. I've seen the MS. But how the hell do I know if I'm supposed to find area in a volume question? :/

How many marks.If its around 3-4 marks there are usually more steps required.

Jab consecutive kaha hai to definitely aise he hoga. I'm actually talking about n.

It's of 4 marks but whatever. How do I know what I've to do in a particular question. I mean how did you know you had to calculate the areas?

calculate:-

AD = BC
i) length of BC.
ii) hieght of trapezium.
iii) total area of shaded region, nearest to cm^2.

all the maths freaks
try doing this the Q neither my class fellows, nor my add maths teacher could solve (though he did it after 20 mins )
but my Maths teacher, obviously, did

Faizan Muhammmad here you go with a Q of my teacher

so n is the actual number .. not a tukka ...which we find by this

use the Pythagoras theorem and you'll get the answer.

Q10...

find the arc length AB (= 90/360 * 2 pie r) and multiply it with the height of the cylinder.

Practice and common sense mostly . If we multiply two lengths we get area,if we multiply area with length we get volume.So first we need area then volume.How else could we have done it?

Hey if interest is yearly and it is of 3 years , shouldnt we multply it thrice?
ms doesnt do that. why just once??

just dont give the answer yet...

its the old one which asad showed around I did it in a few minutes
gave a pretty clear explanation as well

If multiplied thrice wouldnt it become compound interest or something?Just Use PRT/100 and divide by 36....
