Question

A family of 5 persons can be maintained for 20 days with Rs 2,480. Find how long Rs 6944 maintain a family of 8 persons.

Answer 1

Answer:

Total members in 1st case(M) =5

Day(D) =20

Money(₹) =₹2480

In case 2nd members(m) =8

Money(Rs) =₹6944

To find days in 2nd case=d

Using  

MD/₹ =md/rs  

\frac{5 \times 20}{2480}  =  \frac{8 \times d}{6944}  

d =  \frac{5 \times 20 \times 6944}{2480 \times 8}  

d=35days
