thanku mam

awesome thank you AZ

thank u

HAVING gone through this quant which book u strongly recommend

We will find books if get any

Exam requires strong concept building.. If concepts are clear, u can solve easily

R = 15, Y = 9x, G = 4x. Prob of Y = 2/9

So 4x/(15+9x+4x) = 2/9

Solve, x = 3???????????????? is yellow 9x nhi hoga kya??????????????// please es ko explain kru

???????????????????????????

First find balls in each bag. Start with bag A:

R = 15, Y = 9x, G = 4x. Prob of Y = 2/9

So 4x/(15+9x+4x) = 2/9????????????????????????????????????

Solve, x = 3

So in bag A: R = 15, Y = 27, G = 12. Total = 54

Bag B:

G = 2/3 * 27 = 18

Total = 5/6 * 54 = 45

Now 18 + Y + Y â€“ 3 = 45

So, yellow balls = 15, and then red = 12

So in bag B: R = 12, Y = 15, G = 18. Total = 45

Bag C:

R = 1/3 (15+12) = 9

Yellow = 120/100 * 15 = 18

Probability of green ball = 7/16

So z/(9+18+z) = 7/16 [Let z green balls]

Solve, z = 21

So in bag C: R = 9, Y = 18, G = 21. Total = 48

Now probability of yellow ball from each bag = 27/54 * 15/45 * 18/48 = 1/16

No yellow is 4x only.

See in question

Not for that right now

Helloo ma’am..can we olso get memory based questions of reasoning section..

Your dis post is really vry helpful..!! Thnkx a ton

Ok thnkew?

Rhombus PQRS:

sine 30 = (15/2)/Hypotenuse(or side of PQRS)

Solve, Side of PQRS = 15 cm [sine 30 = 1/2]

//…….

sin = perpendicular/hypotenuse………is it correct?

yaha par 15/2 kaise aaya?

PQRS ka ek angle 120 degree hai and 15cm diagonal bisect it then angle 60 degree nahi hoga??means sin 60

I will give the figure for the same.wait for some time

ok ma’am

PQ = 15 cos 60 + 15 cos 60……..two times why??

component needs right angle and for the right angle we need to draw a perpendicular on PQ from point S ….after that we got “PQ= 15cos60 (length from perpendicular to point Q) and x (length from point P to perpendicular) … now we need to calculate x .. so we have another right angle tringle ( we have length of perpendicular and we need to determine base “x” and we have angle SPQ =60 ) so tan60 =15sin60/x …now we can determine the vallue of x and that is 15cos60 also that is why PQ=15cos60+15cos60. hope you will get it .. ðŸ™‚

thank u sir

dont call me sir..!!

i’m also an aspirant ðŸ™‚

in PQRS

cos 60 = base/hypotenus = x/15

1/2 = x/15

x = 15/2 = 7.5

after this what I can do?

Check. I have updated the solution

got it ma’am thank you so much ðŸ™‚

I’m not very internet savvy so I’m not 100% sure.

Any tips or advice would be greatly appreciated. Thanks
