Ratio of Anand and Promode earnings = 32 : 21.

Anand earns Rs. 80/7 in 1 hour.
Promode earns Rs. 90 in 12 hours.

Given:
Anand earns Rs.80 in 7 hours
Promod earns Rs.90 in 12 hours
To find: Ratio of their earnings
Solution:
Let's find out how much they earn in 1 hour
Anand's earning in 1 hour = 80/7
Promod's earning in 1 hour = 90/12
Ratio of their earnings = (Anand's earning in 1 hour) : (Promod's earning in 1 hour)
= (80/7) : (90/12)
Simplify the above ratio by taking LCM of the denominators i.e. 84
Ratio of their earnings = (80/7) : (90/12)
= (80*12) : (90*7)
= 960 : 630
Divide both numbers by 30 to get the simplest form
Ratio of their earnings = 32 : 21
Therefore, the ratio of their earnings is 32 : 21.

Earnings might be different then its okay but here there working hours are also different so = 80/7*12/90=32:21 we reversed 90/12 as 12/90 because hours are different..
