1. Explanation:

   1 / For every correct answer,

   mark is +4

   for 10 correct answer,

   mark is 10×(+4) = +40

   but his mark is +30

   so , (40 – 30 ) = 10

   So, -1 is for 1 incorrect answer

   -10 is for (-10)÷(-1) = 10

   So , Ravi attempted 10 incorrect answer.

   if you try the reverse you will get the second answer too.
