Given: i) 3456+89

ii) 312+8655

iii)74862+51824

To find: The sum by suitable estimation by rounding both to the smaller one's level.

Solution:

Now we have given three terms, so solving one by one each by smaller one's level:

i) 3456+89:

3000+0 . 400+0 . 50+80 . 6+9

= 3000 + 400 + 130 + 15

= 3545

Similarly,

ii) 312+8655

8000+0 . 600+300 . 50+10 . 5+2

= 8000 + 900 + 60 + 7

= 8967

Similarly,

iii) 74862+51824

70000+50000 . 4000+1000 . 800+800 . 60+20 . 2+4

= 120000 + 5000 + 1600 + 80 + 6

= 126686

Answer:

So the value of three terms are: 3545, 8967, 126686
