If A 3 + 8 B = 150, then the value of A + B is
(a) 13
(b) 12
(c) 17
(d) 15

Solution:

A 3

8 B

150

From the above expression we have

B + 3 = 10

B = 7 (1 carries over)

A + 1 + 8 = 15

A = 6

Therefore,

A + B = 13

The correct answer is (a)

✦ Try This: If A 2 + 9 B = 160, then the value of A + B is (a) 13, (b) 14, (c) 16, (d) 15

A 2

9 B

160

B + 2 = 10

B = 8 (1 carries over)

A + 1 + 9 = 16

A = 16 - 10 = 6

A + B = 8 + 6 = 14
