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.

As I have stated in answer, the modal composition of all minerals (olivine+Opx+Cpx+Others) is greater than 100%, which is wrong because modal composition can't be greater than 100%. If you will consider the modal composition of Olivine, Opx and Cpx as 63, 16 and 18% respectively then the modal percentage of other minerals must be 100-(Olivine+Opx+Cpx) = 100-97= 3%.
