QUESTION 1 :-

(i)

$\sf \: 19 - 12 \div (5 + 9\times 2 - 19) \\ \sf = 19 - 12 \div (5 + 18 - 19) \\ \sf \: = 19 - 12 \div (23 - 19) \\ \sf = 19 - 12 \div 4 \\ \sf \: = 19 - \frac{ \cancel{12}}{ \cancel4} \\ { \underline{ \boxed{\sf = 19 - 3 = 16}}}$

(ii) Estimation (nearest tens) of 267 + 132 = 399

= 400 ans.

(iv) Value of $\sf 7^3$

= 7 × 7 × 7 = 343 ans.

(v) 25 × 232 × 4 (suitable arrangement)

= 25 × 4 × 232

= 100 × 232

= 23200 ans.
