find q and r for the following pairs of positive integers a and b satisfying` a = bq+r` `(1)a =13 , b=13 ` `(2)a=8 , b=20` `(3)a=125 , b=5` `(4)a=132 ,b=11`

Explanation

given that, ` a= b*q +r `

in option 1 , given that `a= 13, b=13 `

`13= 13*q + r`

`13*(1-q) = r`

`if q= 0, r= -13`

`if q=1, r= 0`

`if q= 2 , r=-13` not possible

`:.` 2 solutions can be possible.
