Question

if c is the remainder when 999 id divided by 7 and d is the remainder when 777 is divided by 9 what is the remainder when c is divided by d?

Answer 1

hey there !!!


given ;-

if c is remainder when 999 divided by 7

as we know ,

a = bq + r. ( by assuming a = 999 and , b = 7 )
than ,

999 = 7 × 142 + c. ( we assume remainder = c )

999 - 994 = c

therefore , c = 5

and ,,

again doing the same process with the second no.

when 777 is divided by 9 we get d as remainder .

now .,,

putting this in a = bq + r ,,,
where,
a = 777 and , b = 9 and d be the remainder .

777 = 9 × 86 + d

777 - 774 = d

d = 3

therefore d = 3

,,

now ,, what our question saying ;-

what is remainder when , c divided by d then what will be remainder ,,

let us see what it will

c/d = 5/3

5 = 3 × 1 + r

r = 2

hence , when c divided by d we get 2 as remainder .

hope it helps !!! .
