Question

Binny spend Rs a daily and saves Rs b per week. What is her income for two weeks?​

Answer 1

Answer:

Given,

Amount saved by Benny in a week or 7 days = Rs. b

Amount saved by Benny in two weeks or 14 days = b+b

= Rs. 2b

Expenditure of Benny in one day = Rs. a

Expenditure of Benny in a week or 7 days = Rs. 7a

Expenditure of Benny in two weeks = 7a+7a

= 14a

We know that,

The income of a person = Savings of a person + Expenditure of a person

So,

Benny's income for two weeks = Benny's savings for two weeks + Benny's expenditure for two weeks

= Rs. (2b+14a)
