Solution

The correct option is B (i)- $>$ , (ii)- $<$ , (iii)- $>$
(i) $22 \times (- 36) + (- 42) \div (- 3)$

$= 22 \times (- 36) - 42 \times \frac{1}{- 3}$

$= 22 \times (- 36) + 14 = - 792 + 14 = - 778$

Also, $9 \times 56 \times (- 8) = - 4032$

So, $- 778 > - 4032$

$∴ 22 \times (- 36) + (- 42) \div (- 3) > 9 \times 56 \times (- 8)$

(ii) $26 - 22 + 21 \div (- 7)$

$= 26 - 22 + 21 \times \frac{1}{- 7} = 1$

Also, $43 - 11 - 13 = 43 - 24 = 19$

So, $1 < 19$

$∴ 26 - 22 + 21 \div (- 7) < 43 - 11 - 13$

(iii) $- 16 \div [(- 13) + (- 3)]$

$= - 16 \div (- 13 - 3) = (- 16) \div (- 16) = 1$

Also, $12 \div [(- 3) - 0] = 12 \div (- 3) = 12 \times \frac{1}{- 3} = - 4$

$∴ - 16 \div [(- 13) + (- 3)] > 12 \div [(- 3) - 0]$ .
