The incomes of A and B are in the ratio 3:5 and their expenditures are...
Let us say A's income is x and B's income is y.
=> x/y = 3/5
=> y = 5x/3 --- (1)
Now, Income - Expenditure = Savings
=> Expenditure = Income - Savings
A's Expenditure = x - 8000
B's Expenditure = y - 15000
=> (x - 8000)/(y - 15000) = 2/3
=> 3x - 24000 = 2y - 30000
=> 3x - 24000 = 10x/3 - 30000
=> 10x/3 - 3x = 6000
=> x = 18000 and y = 30000
Therefore A's income is Rs 18000 and that of B's is Rs 30000.

Similar Class 10 Doubts

Read the source given below and answer the questions that follows:For comparing countries, their income is considered to be one of the most important attributes. Countries with higher income are more developed than others with less income. This is based on the understanding that more income means more of all things that human beings need. Whatever people like, and should have, they will be able to get with greater income. So, greater income itself is considered to be one important goal. The income of the country is the income of all the residents of the country. This give us the total income of the country. However, for comparison between countries, total income is not such a useful measure. Since, countries have different populations, comparing total income will not tell us what an average person is likely to earn. Are people in one country better off than others in a different country? Hence, we compare the average income which is the total income of the country divided by its total population.The average income is also called per capita income.In World Development Reports, brought out by the World Bank, this criterion is used in classifying countries. Countries with per capita income of US$ 12,056 per annum and above in 2017, are called rich countries and those with per capita income of US$ 955 or less are called low-income countries. India comes in the category of low middle income countries because its per capita income in 2017 was just US$ 1820 per annum. The rich countries, excluding countries of Middle East and certain other small countries, are generally called developed countries.Human Development Report published by UNDP compares countries based on the educational levels of the people, their health status and per capita income.Q. The compares the development of the countries on the basis of literacy rate, gross enrolment ratio and health status of their people.

Read the given extract and answer the questions that follows:Democracies are based on political equality. All individuals have equal weight in electing representatives. Parallel to the process of bringing individuals into the political arena on an equal footing, we find growing economic inequalities. A small number of ultra-rich enjoy a highly disproportionate share of wealth and incomes. Not only that, their share in the total income of the country has been increasing. Those at the bottom of the society have very little to depend upon. Their incomes have been declining. Sometimes they find it difficult to meet their basic needs of life, such as food, clothing, house, education and health. In actual life, democracies do not appear to be very successful in reducing economic inequalities. The poor constitute a large proportion of our voters and no party will like to lose their votes. The situation is much worse in some other countries. In Bangladesh, more than half of its population lives in poverty. People in several poor countries are now dependent on the rich countries even for food supplies.Answer the following MCQs by choosing the most appropriate options:Q. How the share of poor people affects the total income of a democratic country?
