\n(b) 796-314
\n(c) 12,904 + 2,888
\n(d) 28,292-21,496
\nMake ten more such examples of addition, subtraction and estimation of their outcome.
\nAnswer:
\n(a) 730 round off to 700
\n998 round off to 1000
\nEstimated sum = 1700<\/p>\n

(b) 796 round off to 800
\n314 round off to 300
\nEstimated sum = 500<\/p>\n

(c) 12904 round off to 13000

\nEstimated sum = 16000<\/p>\n

(d) 28292 round off to 28000
\n21496 round off to 21000
\nEstimated difference = 7000<\/p>\n

\"NCERT<\/p>\n

Question 2.
\nGive a rough estimate (by rounding off to nearest hundreds) and also a closer estimate (by rounding off to nearest tens):
\n(a) 439 + 334 + 4317
\n(b) 1,08,737-47,599
\n(c) 8325 – 491
\n(d) 4,89,348-48,365
\nMake four more such examples
\nAnswer:
\n(a) Rounding off to nearest hundreds
\n439 round off to 400
\n334 round off to 300
\n4,317 round off to 4,300
\nEstimated sum = 5,000
\nAgain, Rounding off to nearest tens
\n439 \u2192 440
\n334 \u2192 330
\n4,317 \u2192 4,320
\n\u2234 Closer estimate = 440 + 330 + 4,320 = 5,090<\/p>\n

(b) Rounding off to Areas tens
\n= 440 + 330 + 4320 = 5090
\n108737 round off to 108700
\n47599 round off to 47600
\nEstimated difference = 61100
\nAgain, Rounding off to nearest tens
\n1,08,734 \u2192 1,08,730
\n47,599 \u2192 47,600
\n\u2234 Closer estimate=1,08,730 – 47,600 = 61,130<\/p>\n

\"NCERT<\/p>\n

(c) Rounding off to nearest tens
\n= 108730-47600 = 61130
\n8325 round off to 8300
\n491 round off to 500
\nEstimated difference = 7800
\nAgain, Rounding off to nearest tens
\n8,325 \u2192 8,330
\n491 \u2192 490
\n\u2234 Closer estimate = 8,330 – 490 = 7,800<\/p>\n

(d) Rounding off to nearest tens
\n= 8330 – 490 = 7840
\n489348 round off to 489300
\n48365 round off to 48400
\nEstimated difference = 440900
\nAgain, Rounding off to nearest tens
\n4,89,348\u2192 4,89,300
\n48,365 \u2192 48,370
\nCloser estimate=4,89,350-48,370=4,40,980<\/p>\n

Question 3.
\nEstimate the following products using general rule:
\n(a) 578 x 161
\n(b) 5281 x 3491
\n(c) 1291 x 592
\n(d) 9250 x 29
\nMake four more such examples
\nAnswer:
\n(a) 578 x 161
\n578 round off to 600
\n161 round off to 200
\nThe estimated product
\n= 600 x 200 = 1,20,000<\/p>\n

\"NCERT<\/p>\n

(b) 5281 x 3491
\n5281 round of to 5,000
\n3491 round off to 3,500
