Question. 33
Annual salary at r rupees per month along with a festival bonus of Rs 2000 is _________.
Answer:
Annual salary at r rupees per month along with a festival bonus of Rs 2000 is 12r + 2000.
Detailed Answer with Explanation:
Step 1: “r rupees per month” means you earn r every month.
Step 2: One year has 12 months.
So, money from salary in one year is:
( r + r + cdots ext{ (12 times)} )
That is:
( 12 imes r )
( = 12r )
Step 3: There is a one-time festival bonus of Rs 2000.
( ext{Bonus} = 2000 )
Step 4: Total annual amount = yearly salary + bonus
( ext{Total} = 12r + 2000 )
Quick check (example): If ( r = 1000 ), then
( ext{Total} = 12 imes 1000 + 2000 = 12000 + 2000 = 14000 )
Final Answer: ( 12r + 2000 )
