Question

5) Reema saves Rs a daily and spends Rs b daily. Her income is how much in 3 days​

Answer 1

Given data:

• Reema saves Rs. a daily and spends Rs. b daily.

To find:

• How much her income is in 3 days?

Step-by-step explanation:

We must know that the total income in a day is given by the sum of daily savings and daily expenses.

Here, daily savings is Rs. a and daily expenses is Rs. b.

Thus Reema's daily income is Rs. (a + b).

Hence her income in 3 days is Rs. 3(a + b).

Answer 2

SOLUTION

GIVEN

Reema saves Rs a daily and spends Rs b daily.

TO DETERMINE

The income of Reema in 3 days

EVALUATION

Here it is given that Reema saves Rs a daily and spends Rs b daily

Total savings in 3 months = Rs 3 × a = Rs 3a

Now

Total Income = Total savings + Total expenditure

⇒ Total Income = Rs 3a + Rs 3b

⇒ Total Income = Rs ( 3a + 3b )

FINAL ANSWER

$\sf{Total \: Income = Rs. \: ( 3a + 3b ) }$
