A viral question with two answers: a huge sensation

Two answers in  one question

   
This question once went viral on social media

It is  "Two in One"
i.e. one question having two solutions

The original post also says that 
Only 1 in  1000 can do it.

Are you able to find any of the 2 answers?  

Or just confused & wasting hours to try it.

But Solutions are given below: 

First solution:

General representation of above equations
a+b=c

Where c = a+ab. [observation]

i.e 1+ 4(1)=5
     2 + 5(2)= 12
      3 + 6(3)= 21
      8 + 11(8)= 96

Ans : 96

Alternative :

 Add RHS of previous equation to the LHS of next equation this process till no.8 on LHS
Like this,
[Note: we're not treating 8+11=__ as 4th equation]
1+4=5
2+4+5=12
3+6+ 12= 21
4+7+21=32
5+8+32=45
6+9+45=60
7+10+60=77

8+11+77=96

Second sol:

Add RHS of previous equation to the LHS of next equation this process till  4th equation 
[8+11 =__ ]
1+4=5
2+5+5=12
3+6+12=21
Now add 21 in 4th
8+11+21= 40

Ans: 40
