Question
If
have a common factor then 'a' is equal to
- 24
- 1
- 2
- 12
Hint:
In this question we will assume the common root to be 
and so both the equation will be equal using that root in both the equation, so, using this equation we will find the common root. Later putting that root in any one equation we can find the value of a.
The correct answer is: 24

The number of different seven digit numbers that can be written using only the three digits 1, 2 and 3 with the condition that the digit 2 occurs twice in each number is-
We know that there is not much difference between permutation and combination. Permutation is the way or method of arranging numbers from a given set of numbers such that the order of arrangement matters. Whereas combination is the way of selecting items from a given set of items where order of selection doesn’t matter. Both the word combination and permutation is the way of arrangement. Here, we will not use permutation because the order of toys is not necessary.
