Question

A person on tour has Rs 360 for his daily expenses. He decides to extend his tour programme by 4 days which leads to cutting down daily expenses by Rs 3 a day. The number of days of his tour programme is

• A. 15
• B. 20
• C. 18
• D. 16

Answer 1

Answer: (B)

20

Answer 2

Person's daily expenses $=$ Rs $x$
Number of days tour lasts = $y$ days
So, $x \times y=360$
$(x-3)(y+4)=360$
Solving equations (i) and (ii), we get
$y=20$ or $-24$ (not possible)
$\therefore$ $y=20$ days
The correct option is (B)
