Question

what will be replaced in the question mark ?
1-3=2
3-5=12
5-7=30
6-9=?

Answer 1

48 will be the answer

Answer 2

hey user here is your answer:-
the question mark will be replaced by the word 48 because we can see that :-

# In the first one 1-3 = 2
the trick is we will multiply both of them then we get, 1×3 = 3
then we will minus the first one then we get 2 .

# in the second one also we will repeat the same 3×5 = 15
minus the first one i.e. 3 we get 12.

# In the third one also we will repeat the same thing .
we will multiply both of them 5×7 = 35
then minus the first one i.e 5 we get 30.

# same steps we will repeat in the last one :-
multiply 6 and 9 , we get 54 .
then , minus the first one i.e. 6 from 54 we get the required answer i.e. 48

hope it helps you !!!
