Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

For more information refer attached plot. Clearly the gravity reaches it's maximum value (around 1015gal) at a depth of around 2900km . You can see gravity value decreases upto small amount in interval 1000km to 2000km and hence the 1100km lies in the interval, So closest answer will be this only.
