No solution.. agar aap jaise maharathio ka 22 ara hai to ans 22 he hoga! waise ek bar approach btado

Summation till 22
=22*23/2=253
253-198=55
Summation till 10 =10*11/2=55
Hence it starts eating from page 11

summation of 22 = 253
and the count of the insect = 198
so 55 kam hona hai...
summation of 10 = 55
so 11 se 22 tak karegi 😁

Any method without options?

Yaar better try with options only. Otherwise hit nd try with nos greater than 20. I do it this way. There r some other way but i find it faster :)
@ScareCrow28 said:

trial and erorr if no options :D
just check the nearest summation which gives you more than or equal to that number. if it is more keep subtracting from the that tiil you get your sum 😁
A positive three digit number X is such,when divided in two unequal three digit number,the larger part is the aritmetic mean of X and the smaller part.How many values can X take?
a)300 b)234 c)198 d)None

Let, X = pqr = abc + xyz

Now, abc = (pqr + xyz)/2
Solving, we get, pqr = 3*xyz

So, 100 So, 234 values

Please correct me if i am wrong

234 values it is
101 digit number 222.........2X3...333 is formed by repeating the digit 2,50 times followed by the digit X and then repeating the digit 3,50 times.The number is a multiple of 7.Find the value of X.?
a) 2
b) 3
c) 4
d) 5
