Question 8

Choose the alternatives that best replaces the question mark from the given figure?

Solution

$$ 12 \times 3 = 36 $$

$$ 12 \times (3+3) = 12 \times 6 = 72 $$

$$ 12 \times (6+6) = 12 \times 12 = 144 $$

$$ 15 \times 1 = 15 $$

$$ 15 \times (1+1) = 15 \times 2 = 30 $$

$$ 15 \times (2+2) = 15 \times 4 = 60 $$

$$ 14 \times 2 = 28 $$

$$ 14 \times (2+2) = 14 \times 4 = 56 $$

$$ 14 \times (4+4) = 14 \times 8 = 112 $$
