The rate if n/t mins. Convert this to hours => 60t/n. You've the rate and the time is 7.5. Multiply to get A.

7.5 hrs = 7.5*60 mins = 450 mins

1 instrument in t mins
so in 450 mins 450/t inst by 1 worker
we have n workers

so 450* n /t

ans A

Vishu you mistake is
we have 1 instrument in t minutes and not t instruments in 1 minute.
