Mr. Bhaskar is on tour and he has Rs. 360 for his expenses. If he exceeds his tour by 4 days, he must cut down his daily expenses by Rs. 3. for how many days is Mr. Bhaskar on tour?  Choose one.
A) 10 B) 20 C) 30 D) 40 E) 50
If his tour is for x days and he is spending Rs y per day, then   xy= 360 x= 360/y or y= 360/x   (x+4)*(y-3)=360   or   xy +4y -3x-12 =360   or   4y-3x-12=0   4*360/x - 3x -12=0   solving it, we get x=20   ANSWER:20
