Answer 1

Answer:

35 Days.

Step-by-step explanation:

Given Problem:

If Rs 8000 can maintain a family of 4 persons for 40 days. Then how long will Rs 10500 maintains a family of persons?

Solution:

Given that,

Budget = 8000.

Persons = 4.

Sustain for = 40 days.

Average expenses per person will be:

$\sf \dfrac{8000}{40\times 4} comes\;to\;\dfrac{50}{persons}$

Let 'x' be the days,

$\sf \dfrac{10500}{x\times 6} =50$

$\sf x= \dfrac{10500}{300}$

$\sf x = 35\;Days$
