Question

Saket is on tour has Rs. 360 for his expenses. Now if he wants to extend his tour for 4 days, he has to cut down his daily expenses by Rs. 3. Take the original duration of tour as x and find the value of x.

• A. -24
• B. - 20
• C. 20
• D. 24

Answer 1

The correct option is C

20

Original duration of tour =x days
Final duration of tour = x + 4 days
Originally, 1 day expenses =Rs $\frac{360}{x}$
Finally, 1 day expenses =Rs $\frac{360}{x+4}$
According to the question,
$\frac{360}{x}=\frac{360}{x+4}+3$
By solving above equation we get two values 20, -24
(by rejecting negative term ,because days cannot be negative)
