Answer 2

Step-by-step explanation:

note * = square

no.of days×daily expenses=3000

final no of days = 3000/n

original no of days = 3000/n-5

20= 3000/n-5 --3000/n

20(n*-5n) = 3000n-3000n+15000

20n*-100n= 3000n-3000n+ 15000

20n*-100n-15000=0

n*-5n-750=0

n*-30n+25n-750=0

n(n-30)+25(n-30)=0

(n-30)(n+25)=0

n=30 , n= -25

n= -25 is neglected because days cannot me negative .

therefore , n=30
