Sir Some Answers Are Wrong Which I Am Telling You In class 8 imo Question 19- There Is No Word That Can Be Formed From G,R,A And P.Hence Answer Should Be Option b) M Question 23- Minimum Amount Would Be Of Package X The Respective Amounts Are W- 27 X- 20.40 Y- 32.5 Z-24.5 Hence Answer Should Be Option b) Question 35- x+1/x = Root 5 (x+1/x)Whole Square = Root 5 Whole Square x2+1/x2+2 = 5 x2+1/x2 = 3 Now Again Squaring Both The Sides x4+1/x4+2 = 9 x4+1/x4 = 7 Hence Answer Is Option d)

Sir Why Aren"t You Correcting The Answer Keys. I Had Provided The Explanation To You Already For Class 8 IMO Set B. For Question 35 Another Method Is x+1/x = Root 5 x2+1 / x = Root 5 x2+1 = Root 5 * x x2-Root5x +1 = 0 Use Quadratic Formula To Solve It Root 5+Square Root (5-4) / 2 Root 5+1 / 2 And Root 5-1 / 2 Substitute It In Expression x4+1/x4 We Will Get The Result As Follows x = 6.95 So Answer Is 7 Only. And Why You Have Too Much Wrong Answer Keys.Are Teachers Not Able To Understand The Questions Asked In IMO.Then What"s The Problem?????These Answer Keys Confuse The Aspirants.In NSO I Found That 5 Answers Were Different From Official Answers So Please Its My Humble Request That If You Release Answer Keys Please Be Sure That ITS CORRECT

Sir Some Answers Are Wrong Which I Am Telling You In class 8 imo

Question 19- There Is No Word That Can Be Formed From G,R,A And P.Hence Answer Should Be Option b) M

Question 23- Minimum Amount Would Be Of Package X

The Respective Amounts Are

W- 27

X- 20.40

Y- 32.5

Z-24.5

Hence Answer Should Be Option b)

Question 35-

x+1/x = Root 5

(x+1/x)Whole Square = Root 5 Whole Square

x2+1/x2+2 = 5

x2+1/x2 = 3

Now Again Squaring Both The Sides

x4+1/x4+2 = 9

x4+1/x4 = 7

Hence Answer Is Option d)

A lot of wrong answers in class 9 IMO.

Please check.

Sir Why Aren"t You Correcting The Answer Keys.

I Had Provided The Explanation To You Already For Class 8 IMO Set B.

For Question 35 Another Method Is

x+1/x = Root 5

x2+1 / x = Root 5

x2+1 = Root 5 * x

x2-Root5x +1 = 0

Use Quadratic Formula To Solve It

Root 5+Square Root (5-4) / 2

Root 5+1 / 2

And Root 5-1 / 2

Substitute It In Expression x4+1/x4

We Will Get The Result As Follows

x = 6.95

So Answer Is 7 Only.

And Why You Have Too Much Wrong Answer Keys.Are Teachers Not Able To Understand The Questions Asked In IMO.Then What"s The Problem?????These Answer Keys Confuse The Aspirants.In NSO I Found That 5 Answers Were Different From Official Answers So Please Its My Humble Request That If You Release Answer Keys Please Be Sure That ITS CORRECT
