Question

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

Answer 1

It is given that Binny spends Rs. a in one day.

$\therefore$ Money spent by him in one week = 7 $\times$ a = 7a

It is further given that he saves Rs. b in one week; therefor we have:

Total income in one week = Total expenditure in one week + Total saving in one week
= 7a + b

$\therefore$ Binny's total income in 2 weeks = 2 $\times$ (7a + b) = Rs. (14a + 2b)
