Question

If a – b = 12and $b over 2$ = 10, what is the value of a + b ?

2
12
32
52

The correct answer is: 52

HINT – Find the values of a and b
SOLUTION – It is given that $b over 2$ = 10
$rightwards double arrow$ b = 20
Also, a – b = 12 $rightwards double arrow$ a = 12 + b
$rightwards double arrow$ a = 12 + 20 = 32
According to question, a + b = 32 + 20 = 52
Hence, option D is correct
