EXERCISE:1.3

1. Estimate each of the following using general rule.

Make ten more such examples of addition, subtraction and estimation of their outcome. 

(a) $730 + 998$

Ans: By general rule

$730$ is round off to nearest hundred $700$ 

$998$ is round off to nearest hundred $1000$

Estimated sum $ = 700 + 1000$

$ = 1700$

(b) $796 - 314$

Ans: By general rule

$796$ is round off to nearest hundred $800$

$314$ is round off to nearest hundred $300$

Estimated difference $ = 800 - 300$

$ = 500$

(c) $12,904 + 2,888$

Ans: By general rule

$12904$ is round off to nearest hundred $12900$

$2888$ is round off to nearest hundred $2900$

Estimated sum $ = 12900 + 2900$

$ = 15800$

(d) $28,292 - 21,496$

Ans: By general rule

$28292$ is round off to nearest hundred $28300$

$21496$ is round off to nearest hundred $21500$

Estimated difference $ = 28300 - 21500$

$ = 6800$


2. Give a rough estimate (by rounding off to nearest hundreds) and also a closer estimate (by rounding off to nearest tens):

Make four more such examples.

(a) \[{\text{439 + 334 + 4317}}\]

Ans: Round off to hundreds

By general rule

$439$ is round off to nearest hundreds $400$

$334$ is round off to nearest hundreds $300$

$4317$ is round off to nearest hundreds $4300$

Estimated sum $ = 400 + 300 + 4300$

$ = 5000$

Round off to tens

By general rule

$439$ is round off to nearest tens $440$

$334$ is round off to nearest tens $330$

$4317$ is round off to nearest tens $4320$

Estimated sum $ = 440 + 330 + 4320$

$ = 5090$

Rounding off to nearest hundreds$ = 5000$

Rounding off to nearest tens$ = 5090$

(b) \[1,08,737 - 47,599\]

Ans: Round off to hundreds

By general rule

$1,08,737$ is round off to nearest hundreds $1,08,700$

$47,599$ is round off to nearest hundreds $47,600$

Estimated difference $ = 1,08,700 - 47,600$

$ = 61,100$

Round off to tens

By general rule

$1,08,737$ is round off to nearest tens $1,08,740$

$47,599$ is round off to nearest tens $47,600$

Estimated difference $ = 1,08,740 - 47,600$

$ = 61137$

Rounding off to nearest hundreds$ = 61100$

Rounding off to nearest tens$ = 61137$

(c) \[8325 - 491\]

Ans: Round off to hundreds

By general rule

$8,325$ is round off to nearest hundreds $8,300$

$491$ is round off to nearest hundreds $500$

Estimated difference $ = 8,300 - 500$

$ = 7800$

Round off to tens

By general rule

$8,325$ is round off to nearest tens $8,330$

$491$ is round off to nearest tens $490$

Estimated difference $ = 8330 - 490$

$ = 7840$

Rounding off to nearest hundreds$ = 7800$

Rounding off to nearest tens$ = 7840$

(d) \[4,89,348 - 48,365\]

Ans: Round off to hundreds

By general rule

$4,89,348$ is round off to nearest hundreds $4,89,300$

$48,365$ is round off to nearest hundreds $48,400$

Estimated difference $ = 4,89,300 - 48,400$

$ = 4,40,900$

Round off to tens

By general rule

$4,89,348$ is round off to nearest tens $4,89,350$

$48,365$ is round off to nearest tens $48,370$

Estimated difference $ = 4,89,350 - 48,370$

$ = 4,40,980$

Rounding off to nearest hundreds$ = 4,40,900$

Rounding off to nearest tens$ = 4,40,980$


3. Estimate the following products using general rule:

Make four more such examples.

(a) $578 \times 161$

Ans: By general rule

\[578\] is round off to nearest hundred $600$

$161$ is round off to nearest hundred $200$

Estimated product $ = 600 \times 200$

$ = 1,20,000$

(b) $5281 \times 3491$

Ans: By general rule

\[5,281\] is round off to nearest hundred $5,300$

$3,491$ is round off to nearest hundred $3,500$

Estimated product $5,300 \times 3,500$

$ = 1,85,50,000$

(c) $1291 \times 592$

Ans: By general rule

\[1,291\] is round off to nearest hundred $1,300$

$592$ is round off to nearest hundred $600$

Estimated product $ = 1300 \times 600$

$ = 7,80,000$

(d) $9250 \times 29$

Ans: By general rule

\[9,250\] is round off to nearest hundred $9,300$

$29$ is round off to nearest tens $30$

Estimated product $ = 9300 \times 30$

$ = 2,79,000$
