Manav's average earning per month in the first three months of a year was ₹76096. In April, his earning was 75% more than the average earning in the first three months. If his average earning per month for the whole year is ₹94660, then what will be Manav's average earning (in ₹) per month from May to December?

Correct option is C

Given:

Average earning per month for the first three months (January to March): ₹76,096

Earnings in April are 75% more than the average earnings of the first three months.

Manav's average earnings per month for the entire year (12 months) are ₹94,660. 

Solution:

The total earnings for the first three months is calculated as:

Total earnings for first 3 months = 76,096 × 3 = 228,288

So, his earnings in April are:

Earnings in April = 76,096 + (0.75 × 76,096) = 76,096 + 57,072 = 133,168

Therefore, the total earnings for the entire year (12 months) is:

Total earnings for the whole year = 94,660 × 12 = 1,135,920

Total earnings for first 4 months = 228,288 + 133,168 = 361,456 

Total earnings from May to December = 1,135,920 − 361,456 = 774,464

Average earnings from May to December = $$\frac{774464}{8}$$  = 96,808

​Manav's average earning per month from May to December is ₹96,808.​
