I would have gone about this a totally different way.
Why not 3*4*4*4*4 = 768?

let's just take the first three levels, these are the possible combinations, correct?
1-1
1-2
1-3
1-4
2-1
2-2
2-3
2-4
3-1
3-2
3-3
3-4
etc...


Maybe I don't understand the question...

Agree with 19 (assuming the levels are exclusive)

If the levels are such that you play level1 and then proceed to level2...level3 and so on... upto 5th level to win the game, then it is "none of the above" It will be 3*4*4*4*4 = 768

What is the OA? OE?

From the question, total scenarios= 3+4+4+4+4 =19
does it mean this the the number of games one can play?

Would go with E.

"How many games are possible" = In how many ways the game can be played ?

Which is = 3*4*4*4*4.

In general, it would be nice if the TOPIC's admin/originator posts OA faster.

This is like a nail biting finish. One keeps checking, if the answer is right or wrong. lol...
