Question

Choose the smallest value from the following statements:

• A. 5 x 10
• B. 3 x 12
• C. 4 x 10
• D. 2 x 19

Answer 1

The correct option is B 3 x 12

5 x 10 = 50
4 x 10 = 40

To find 3 x 12, split 12 as 10 and 2, and multiply 3 by both of them.

12 = 10 + 2

3 x 10 = 30
3 x 2 = 6

30 + 6 = 36

$\therefore$ 3 x 12 = 36

Similarly, 2 x 19 = 38

Thus, the smallest value of the given statements is 3 x 12.
