$\mathfrak{\large{\underline{\underline{Explanation :-}}}}$

Solution :

It is Given that =

111+111= 6

121+121= 8

151+151= ???

If we look at this mathematical Statements for the first, it seems confusing as addition of 3 digits is resulting to one or two digit answer.

But the actual logic is, the numbers which are to be added, their ones, tens and hundreds places are added and then the normal Addition takes place.

$\textbf{\large{\underline{Statement I :}}}$

111 + 111 = 6

Add the ones, tens and hundreds places of 111 and 111

$\implies$ (1 + 1 + 1) + (1 + 1 + 1)

$\implies$ 3 + 3

$\implies$ 6

.°. 111 + 111= 6 is true

$\rule{300}{1.2}$

Statement II $\textbf{\large{\underline{}}}$

121+121= 8

$\implies$ (1 + 2 + 1) + (1 + 2 + 1)

$\implies$ 4 + 4

$\implies$ 8

.°. 121 + 121 = 8 is true

$\rule{300}{1.2}$

$\textbf{\large{\underline{Statement III}}}$

151+151= ???

$\implies$ (1 + 5 + 1) + (1 + 5 + 1)

$\implies$ 7 + 7

$\implies$ 14

★ 151 + 151 = 14

.°. 151 + 151 = 14
