a number when divided by a certain divisor left remainder 245, when twice the number was divided by the same divisor, the remainder was 112. find the divisor?
subtract(multiply(245, const_2), 112)
"easy solution : n = dq 1 + 245 2 n = 2 dq 1 + 490 - ( 1 ) 2 n = dq 2 + 112 - ( 2 ) as ( 1 ) = ( 2 ) = 2 n d * ( q 2 - 2 q 1 ) = 378 d * some integer = 378 checking all options only ( a ) syncs with it . answer a"
