Question

The average earning of each member of the Ambani family is 20% less than the average earning of each member of the Sahara family and the total earning of Ambani's family is 20% more than the total earning of Saharas's family. The no of family members in the Sahara is what percent of the no of family members of Ambani

Answer 1

Step-by-step explanation:

Given The average earning of each member of the Ambani family is 20% less than the average earning of each member of the Sahara family  

Let the members of Ambani family be a and members of the Sahara family be s

Now average earning of a member of Sahara family is 100 and therefore average earning of Ambani family is 80

So total earning of Sahara family = 80 a and earning of Ambani family will be 100 s

According to the question

80 a – 100 s = 20% of 100 s

80 a – 100 s = 20 s

80 a = 120 s

Or s = 2/3 of 100

So s = 66.66 % of a
