​Pranjal's average earning per month in the first three months of a year was ₹19008. In April, his earning was 50% more than the average earning in the first three months. If his average earning per month for the whole year is ₹99708, then what will be Pranjal's average earning (in ₹) per month from May to December?

Correct option is B

Given:

Pranjal’s average monthly income in first three months = ₹19008

Her income in month of A pril = 50% more than average of three months

Total average of whole year = ₹99708

Formula Used:

Average =$$\frac{Sum \ of \ obsrvations}{Number\ of \ observations}$$​​

Solution:

Total income of Pranjal in three months = 19008 $$\times$$​ 3 = ₹57024

Income in April = 19008 + 50\% of 19008 = ₹28512

Total salary of whole year = 99708 $$\times$$​ 12 = ₹11,96,496

Total salary from May to December = 11,96,496 - (57024 +28512) = ₹11,10,960

Average salary from May to December = $$\frac{11,10,960}{8}$$ = ₹1,38,870
