Raghav’s average earning per month in the first three months of a year was Rs.45.000. In April. his earning was $$33 \frac{1}{3}$$​% more than the average earning in the first three months. If his average earning per month for the whole year is Rs.45.300. then what will be Raghav’s average earning (in Rs.) per month from May to December?

Correct option is D

Given:

Raghav’s average monthly income in first three months = ₹45000

His income in month of April = $$33\frac{1}{3}$$​% more than average of three months

Total average of whole year = ₹45300

Formula Used:

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

Solution:

Total income of Raghav in three months = 45000 $$\times$$​ 3 = ₹135000

Income in April = $$45000 + \frac{100}{3}\% \ of \ 45000$$ = ₹60,000

Total salry of whole year = 45300 $$\times$$​ 12 = ₹543600

Total salary from May to December = 543600 - (135000 + 60000) = ₹348600

Average salary from May to December =$$\frac{348600}{8} =₹43,575$$​​
