Correct Answer - Option 4 : 20
IPHONE = 1
Consider A = 1, B = 2, C = 3, D = 4 and so on...
I + P + H = 9 + 16 + 8
= 33
O + N + E = 15 + 14 + 5
=34
now, 34 - 33 = 1
Similarly,
K + I + D = 11 + 9 + 4
= 24
N + E + Y = 14 + 5 + 25
= 44
now, 44 - 24 = 20
Implies LIMITED = 20
Hence, the correct answer is 20.
