1. Answer:

   2

   Step-by-step explanation:

   if 9 is divided by n then remainder = 7

   let assume quotient as – p

   dividend = n

   dividend = divisor×quotient+remainder

   dividend = 9p+7

   lets assume p as 1

   so, 9×1+7

   = 16

   now we have – 3n-1 ÷ 9

   So, 3 × 16 – 1

   = 47

   47 ÷ 9

   remainder = 2

   hence, 2 is the answer..
