The divisibility rule of 10 states that If the last digit of a number is 0 then the given number is divisible by 10.
For Example: Check whether 5400 is divisible by 10 or not?
Solution:
As the last digit of the number is 0 hence, 5400 is divisible by 10
Here are Few Examples Illustrated on the Divisibility Rule of 10:
1. Check whether the following numbers are divisible by 10 or not and state why?
(i) 8500
(ii) 4213
(iii) 1478
(iv) 33060
(v) 850
(vi) 4230
(vii) 45822
(viii) 1008
(ix) 7400
(x) 3090
(xi) 6010
(xii) 4512
(xiii) 8500
(xiv) 6302
(xv) 2450
(xvi) 4400
(xvii) 5063
(xviii) 4710
(xix) 2050
(xx) 7475
Solution:
(i) 8500
Since the last digit is 0 hence, 8500 is divisible by 10
(ii) 4213
As, the last is 3 hence, 4213 is not divisible by 10
(iii) 1478
The last digit is 8 so, 1478 is not divisible by 10
(iv) 33060
As, the last digit is 0 hence, 33060 is divisible by 10
(v) 850
The last digit is 0 hence, 850 is divisible by 10
(vi) 4230
Last digit is zero hence, 4230 is divisible by 4230
(vii) 45822
The last digit is 2 hence, 45822 is not divisible by 10
(viii) 1008
The last digit is 8 hence; the number is not divisible by 10
(ix) 7400
7400 has 0 as the last
digit so 7400 is divisible by 10
(x) 3090
3090 has last digit 0 hence, 3090 is divisible by 10
(xi) 6010
The last digit is zero hence 6010 is divisible by 10
(xii) 4512
The last digit is 2 hence, 4512 is not divisible by 10
(xiii) 8500
The last digit is 0 hence, 8500 is divisible by 10
(xiv) 6302
The last digit is 2 hence, 6302 is not divisible by 10
(xv) 2450
The last digit is 0 hence, 2450 is divisible by 10
(xvi) 4400
The last digit is 0 hence, 4400 is divisible by 10
(xvii) 5063
The last digit is 3, hence 5063 is not divisible by 10
(xviii) 4710
The last digit is 0 hence, 4710 is divisible by 10
(xix) 2050
The last digit is 0 hence, 2050 is divisible by 10
(xx) 7475
In 7575 the last digit is 5 hence, 7475 is not divisible by 10
2. Rewrite the series with numbers that are divisible by 10 in a different color:
7850 9600 3050 1008 5420 45686 4730
Solution:
7850 9600 3050 1008 5420 45686 4730
3. Fill in the blanks with digits so as to make the following numbers divisible by 10:
(i) 78 … 0
(ii) 857 …
(iii) … 560
(iv) 110 …
(v) 630 …
(vi) 4 … 20
(vii) 3 … 40
(viii) 830 …
(ix) 408 …
(x) 753 …
Solution:
(i) 7830
(ii) 8570
(iii) 8560
(iv) 1100
(v) 6300
(vi) 4220
(vii) 3440
(viii) 8300
(ix) 4080
(x) 7530
