Sorry i m bio student…
No worries! Thanks…
bro the first question use standard limits bro if you don’t get it then ill send you the solution
Thanks yaar… @Sanjay_S
Check this out👆
2nd one…any idea?
try kartha hun a bit held up now will try later
Check the qn pls. I mean r=1 to r=_
Even I thought the same thing…maybe it’s just hit and trial after this👇
@Ankit_Kumar … Which option do you think is correct…?
Bhai koi bhi option match nhi kar RHA h🤔
Sahi kaha…maybe something is wrong with question…
Thanks for checking @Ankit_Kumar
For first i assumed x number of fours , y number of sixes and z number of dot balls
X+y+z=20 and 4x+6y=100
Solving we get y=10+2z and i just put random values for z until x,y,z doesnt exceed 20. Any other methods to solve this Q apart this?
For second please provide a short approach too ,

EDIT: only ellipse one is left. The one thats not blurred. Please try.
For the first question: I didn’t calculate but you may try this method. Since you found two equations you may add them to get one equation.
I took infinite series because there are no restrictions on the number of sixes, fours or dot balls.
For question 47 , i did this but getting wrong answer , please tell me my mistake
@Cooljet123 @LaveshGupta @Rudra_d
Edit: Doubt Solved.
There is , they have to be less than 20
Ok then restrict the terms. Sorry I didn’t notice.
Bro! A coincidence ! I was solving the same paper in morning and doing the rest now and correctly you asked these!
Anyone please tell Q47 first , what mistake did i did there.
I may have done something wrong in area equations.
