3...!
see.. let x be no of attempted questions, y be no of incorrect, z be no of not attempted...
total = 50.. => x+y+z=50..
and also x-(y/3)-(z/6)=32... (as 1/3 marks are deducted for incorrect ones and 1/6 marks are deducted for not attempting a question.. )
solve these two .. u will get y=7x-242... substitute the nearest poss integer.. 35*7-242= 3.. implies.. 35 were correct.. 3 were wrong.. 12 were not attempted..
