ANSWER

Shantanu decided to collect money for buying motorcycle whose cost is Rs. 200000. The initial amount in his bank account is Rs. 50000. On the basis of past drives , it is determined that after t months the beginning of the drive , the rate at which money is arranged for his motorcycle is proportional to the difference between the desired goal of Rs. 200000 and the total amount x in the bank account at that time . After one month , a total of Rs. 100000 is in the bank account . Now answer the following questions using differential equation method : (i) What is the differential equation created ? (a) = k ( 200000 – x) (b) = k ( 100000 – x) ( c) = k ( 60000 – x) (d) = k
