take da consecutive nos to b  a-3, a-2, a-1, a, a+1, a+2


add all of dem ull get 6a-3=27(given sum of all da nos is 27)


therefore a=5


largest no =a+2


so largest no =7

first test % is 60 let it be 60 out of hundred
and 4 the last, it is 75% so 75/100
difference is 15%
hence he improved by 15%
