If A 3 + 8 B = 150, then the value of A + B is


According to the question;


In one’s place B + 3 = 0


B is the number whose addition with 3 gives 0 in a one’s place.


B = 7 (7 + 3 = 10 and one’s place of 10 is 0 )


In ten’s place A + 8 + 1 = 15 ( 1 is the carry from B + 3)


A + 9 = 15


A = 15 – 9 = 6


A + B = 6 + 7 = 13.


Hence the option (a) is correct.
