If 1 1 1 1= R 2 2 2 2= T 3 3 3 3= E 4 4 4 4= NThen 5 5 5 5= ??? Solution:-

CRACK THE LOGIC IF U R SMART ENOUGH

If 1 1 1 1= R
    2 2 2 2= T
    3 3 3 3= E
    4 4 4 4= N
Then 5 5 5 5= ?

Solution:-

1+1+1+1 = 4 = R

Write in English of 4 = FOU[R] .

[ R ] is the last letter of fOUR.

Again apply same process

2+2+2+2 = 8 = T

[ T ] Is the last letter of EIGHT.

3+3+3+3 = 12 = E

[ E ] is the last letter of TWELVE.

4+4+4+4 = 16 = N

[ N ] is the last letter of SIXTEEN.

So

  5+5+5+5 = 20 = Y

Because [ Y ] is the last letter of TWENTY.

.°. Y is the right answer.
