If the present age of Ramandeep is n years, then her age after 7 years will be _________.
If the present age of Ramandeep is n years, then her age after 7 years will be n + 7.
Step 1: “Present age” means the age right now. It is given as (n) years.
Step 2: “After 7 years” means we add (7) years to the present age.
Step 3 (write the idea):
Future age = Present age + 7
Step 4 (substitute):
Present age = (n)
So, Future age = (n + 7)
Quick check: If (n = 10), after 7 years it becomes (10 + 7 = 17). This matches the rule (n + 7).
