If a family including 5 persons can be maintained for 20 days Rs. 2480. Then;
8 persons maintained for 20 days will be- 8 * 2480 / 5= Rs 3968

 Conclusion    8 persons will be maintained for 20 days with Rs 3968

Then,
Rs. 6944 * 20 / 3968 = 35 days 
Ans. Rs. 6944 will maintain a family of 8 persons for 35 days.
