 Hello and welcome to the session. In this session we discuss the following question which says, Ram earns Rs. 15,000 per month. He spends 1 upon 3 of his income on food, 3 upon 10 of the remainder on house rent, and 3 upon 20 of the remainder on the education of the children. How much money is still left with him? Let's move on to the solution. In the question we are given that Ram's income is equal to Rs. 15,000 per month. Next we have that he spends 1 upon 3 of his income on food. So we say, income on food is equal to 1 upon 3 into Rs. 15,000. Now, 3 5,000 times is 15,000. So this would be equal to Rs. 5,000. That is, income spent on food is Rs. 5,000. So now remaining money would be equal to his income that is Rs. 15,000 minus income spent on food which is Rs. 5,000 and this is equal to Rs. 10,000. Then next we have he spends 3 upon 10 of the remainder on house rent. So next we have money spent on house rent is equal to 3 upon 10 into the remaining money that is Rs. 10,000. Now this 0 cancels with this 0 and this would be equal to Rs. 3,000. So he spends Rs. 3,000 on house rent. Now let's again calculate the remaining money with him. So remaining money with Ram would be equal to this money that is Rs. 10,000 minus money spent on house rent that is Rs. 3,000 and this is equal to Rs. 7,000. Now Ram has Rs. 7,000 left with him. Next in the question is given that he spends 3 upon 20 of the remainder on the education of the children. So money spent on education is equal to 3 upon 20 multiplied by the remaining money with Ram that is Rs. 7,000. Now this 0 cancels with this 0 and 352 times is 700. So this is equal to Rs. 3 into 350 which would be equal to 1,050. So money spent on education is Rs. 1,050. Now from the Rs. 7,000 left with him he has spent Rs. 1,050 on education. So next we say that money remaining with Ram is equal to Rs. 7,000 minus Rs. 1,050 which is for the equal to Rs. 5,950. So now money left with Ram is Rs. 5,950. Thus our final answer is money left with Ram is equal to Rs. 5,950. So this completes the session. Hope you have understood the solution for this question.
