Q.1 Estimate each of the following using general rule:

(a) 730 + 998 (b) 796 – 314 (c) 12,904 +2,888 (d) 28,292 – 21,496

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

Ans.

(a) 730 + 998

We round off the given numbers to hundreds.

Number 730 rounds off to 700 and 998 rounds off to 1000.

Therefore,

Estimated sum = 700 + 1000 = 1700

(b) 796 – 314

We round off the given numbers to hundreds.

Number 796 rounds off to 800 and 314 rounds off to 300.

Therefore,

Estimated difference = 800 – 300 = 500

(c) 12904 + 2888

We round off the given numbers to thousands.

Number 12904 rounds off to 13000 and 2888 rounds off to 3000.

Therefore,

Estimated sum = 13000 + 3000 = 16000

(d) 28,292 − 21,496

We round off the given numbers to thousands.

Number 28,2962 rounds off to 28000 and 21,496 rounds off to 21000.

Therefore,

Estimated difference = 28000 − 21000 = 7000

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

(a) 439 + 334 + 4,317
(b) 1,08,734 – 47,599
(c) 8325 – 491
(d) 4,89,348 – 48,365

Make four more such examples.

Ans.

(a) 439 + 334 + 4317

We round off the given numbers to hundreds.

Number 439 rounds off to 400, 334 rounds off to 300 and 4317 rounds off to 4300.

Therefore,

Estimated sum = 400 + 300 + 4300 = 5000

Now, we round off the given numbers to tens.

Number 439 rounds off to 440, 334 rounds off to 330 and 4317 rounds off to 4320.

Therefore,

Estimated sum = 440 + 330 + 4320= 5090

(b) 1,08,734 − 47,599

We round off the given numbers to hundreds.

Number 1,08,734 rounds off to 1,08,700 and 47,599 rounds off to 47,600.

Therefore,

Estimated difference = 1,08,700 – 47,600 = 61,100

Now, we round off the given numbers to tens.

Number 1,08,734 rounds off to 1,08,730 and 47,599 rounds off to 47,600.

Therefore,

Estimated difference = 1,08,730 – 47,600 = 61,130

(c) 8325 − 491

We round off the given numbers to hundreds.

Number 8325 rounds off to 8300 and number 491 rounds off to 500.

Therefore,

Estimated difference = 8300 – 500 = 7,800

Now, we round off the given numbers to tens.

Number 8325 rounds off to 8330 and number 491 rounds off to 490.

Therefore,

Estimated difference = 8330 – 490 = 7,840

(d) 4,89,348 − 48,365

We round off the given numbers to hundreds.

Number 4,89,348 rounds off to 4,89,300 and number 48,365 rounds off to 48,400.

Therefore,

Estimated difference = 4,89,300 – 48,400 = 4,40,900

Now, we round off the given numbers to tens.

Number 4,89,348 rounds off to 4,89,350 and number 48,365 rounds off to 48,370.

Therefore,

Estimated difference = 4,89,350 – 48,370 = 4,40,980

Q.3 Estimate the following products using general rule:

(a) 578 × 161
(b) 5281 × 3491
(c) 1291 × 592
(d) 9250 × 29

Make four more such examples.

Ans.

(a) 578 × 161

We round off the given numbers to hundreds.

Number 578 rounds off to 600 and number 161 rounds off to 200.

Therefore,

Estimated product = 600 × 200 = 1,20,000

(b) 5281 × 3491

We round off 5281 to nearest thousands and so 5281 rounds off to 5000.

We round off 3491 to nearest hundreds and so 3491 rounds off to 3500.

Therefore,

Estimated product = 5000 × 3500 = 1,75,00,000

(c) 1291 × 592

We round off the given numbers to hundreds.

Number 1291 rounds off to 1300 and number 592 rounds off to 600.

Therefore,

Estimated product = 1300 × 600 = 7,80,000

(d) 9250 × 29

We round off 9250 to 9000 and 29 to 30.

Therefore,

Estimated product = 9,000 × 30 = 2,70,000
