Solution:

Let Mr. Ankit is on tour for days
⇒ Original daily expense = Rs.

360/x

According to ques,
⇒

(x + 4)( 360 /x − 3) = 360

⇒

360 − 3x +1440/ x − 12 = 360

⇒

3x − 1440/x + 12 = 0

⇒

3x^2 + 12x − 1440 = 0

⇒

x^2 + 4x − 480 = 0

⇒

x^2 + 24x − 20x − 480 = 0

⇒

x(x + 24) − 20(x + 24) = 0

⇒

(x + 24)(x − 20) = 0

⇒

x = −24, 20

∵ x cannot be negative , ⇒

x=20
