121+121=8
151+151=x
find the x value
a. 302
b.5
c.14
d.28​

Answer 1

${\huge{\underbrace{\pink{\bf{Answer\checkmark}}}}}$

$\longrightarrow \: 111 + 111 = 6$

$\longrightarrow \: 121 + 121 = 8$

$\longrightarrow \: 151 + 151 = \rm x$

We can notice that

• in 1st , 111 + 111 = 6

here , all the digits are added → (1+1+1)+(1+1+1)→ 6

________________________

• in 2nd , 121 + 121 = 8

here also , all the digits are added → (1+2+1)+(1+2+1) → 8

____________________________

• So , similarly , in 3rd , add all the digits

(1+5+1)+(1+5+1) = 7+7 = 14

$\huge \boxed { \rm x = 14}$

Option C (14) is correct
