Let the monthly salary of the man be Rs. ‘x’. Money spent on rent and transportation = (20 + 10)% of x = Rs. 0.30x Remaining money = (x – 0.30x) = Rs. 0.7x Money spent on food and entertainment = (25 + 40)% of 0.7x = Rs. 0.455x Remaining money left = 0.7x – 0.455x = 0.245x So, 0.245x = 3675 x = Rs. 15000
