(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
<\/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
<\/p>\n
(b) 5281 x 3491 \n5281 round of to 5,000 \n3491 round off to 3,500 \nThe estimated product \n= 5,000 x 3,500 = 1,75,00,000<\/p>\n
(c) 1291 x 592 \n1291 round off to 1300 \n592 round off to 600 \nThe estimated product \n= 1300 x 600 = 7,80,000<\/p>\n
(d) 9250 x 29 \n9250 round off to 10,000 \n29 round off to 30 \nThe estimated product \n= 10,000 x 30 = 3,00,000<\/p>\n","protected":false},"excerpt":{"rendered":"
