Raman sir , is this solution right ? only 2.8 satisfies the equation since it is a 3rd degree polynomial x will have three values and all the three va...

I have got it as 8^3-1/8^3+1 ...... And so on but what to do next ?

Hi Utkarsh, I can suggest you this We don't know whose speed is greatest so we have to assume cases Let speed be R ,G,S Case 1 - R>G>S R-S= D/...

Hi Richa, You can always go by options Putting x=-4 we get (12,16,-16) Max of them is 16 Putting x=-2 we get (0,8,-8) Max of them is 8 Putting x=1 we...

40 ?

2.8 ?

24 is the answer its under root will b around 4.9 and natural no.s less than 4.9 are 4,3,2,1 and all are divisible by 24

Since 5001 is odd term the sequence will end with 1 written (n+1) times where (n+1) is odd Sum will be something like 1 +2(1)+3(1)..... n times + 7...

You can do by checking options 1st and last doesn't satisfy your equation And your equation suggests that x^2>4 and x<4 4<x^2<16 check ...

this has been told earlier by Raman sir

where are P and Q points and what is the use of EF ?

for infine sum S= lim n->∞ Sn applying limits since 1/n is 0 if n tends to ∞ S= 1/2(1-0) S=1/2 (answer)
