11
84=3*4*7
So minimum total of 2+3+6 =11 cuts

Aisa mat bolo sir nai to muje b delete karna pad jaega 😛
Anyways i throw this upon you guys:

For every positive even integer n, the function h(n) is defined to be the product of all even integers from 2 to n, inclusive. If p is the smallest prime factor of h(100) +1, then p is
A. between 2 and 10
B. between 10 and 20
C. between 20 and 30
D. between 30 and 40
E. Greater than 40

@chandrakant.k bhai main toh samjha raha tha isliye kaha
ha pata hai bhai.. i just added in case you do not know 😃
Calvin and David play a game of dice. They both throw fair 6-sided dice. The probability that the number on the David's dice is bigger than the number on Calvin's dice is ab, where a and b are positive coprime integers. What is the value of a+b?
No OA pls help
@ScareCrow28 Is it option A? p=5?

2^50*50! + 1 = number

so, any number 40

how can the prob be "ab" with a and b both integers samajh nai aya..
Probablility is coming out to be 5/12 na?
Is it ab or a/b ?? It should be a/b...please confirm

D. between 30 and 40
E. Greater than 40

N = 2^50*50!
N+1/x will leave remainder 1 for all numbers till 50
hence it should be greater than 50 at least
