Question

rohan spend rs. x daily and saves rs. y per day. what is his income after 3 weeks? Ans 21(x+y)​

Answer 1

Answer:

21(x + y)

Step-by-step explanation:

Rohan's expenditure for one day = Rs. x

Rohan's savings for one day = Rs. y

Income = Expenditure + Savings = x + y

So, Rohan's income for one day = Rs. (x + y)

3 Weeks = 21 days

Rohan's income for 21 days = 21 × (x + y) = Rs. 21(x + y)

Answer 2

Answer:  This the Step By Step Solution :)

Step-by-step explanation:

So we know that 3 weeks = 21 days ( 3 * 7 days)

The amount he spends for 21 days = 21x

The amount he saves for 21 days = 21y

so the total amount = 21x + 21y

                                 = 21 (x+y)     [ taking 21 common]
