The correct answer is: ⇒ x = 14

○ Given:
Aaryan has Rs 50 and saves Rs. 5.50 each week.
Charan has Rs 18.50 and saves Rs. 7.75 each week..
○ Step 1:
○ Let the number of weeks after week they have same amount be x.
So, after x week Aaryan saving will be equal to,
50 + 5.50x
And, after x weeks charan saving will be equal to,
18.50 + 7.75 x
○ Step 2:
○ Equate the saving of Aaryan and Charan.
50 + 5.50x = 18.50 + 7.75 x
50 - 18.50 = 7.75x - 5.50x
31.50 = 2.25x
x = 
x = 14

• Final Answer:
