 Hello and welcome to the session. In this session we are going to discuss the following question and the question says that the recommended daily intake i.e. RDI of iron is 18 mg. One day Anna determined that she consumed 26 mg of iron. What percent of RDI did she consume? Let us start with the solution of the given question. Here we are given that recommended daily intake of iron is 18 mg and Anna consumed 26 mg of iron and we have to find what percent of RDI that is recommended daily intake did she consume. Now here percentage of RDI should be equal to the amount consumed by Anna that is we have to find what percent of 18 is equal to 26. Now suppose she consumed p percent of RDI that is p percent of 18 should be equal to 26. This implies that p upon 100 into 18 is equal to 26 that is 18 p upon 100 is equal to 26. Now we have to solve this equation for p. Now we multiply by 100 on both sides and we get 18 p upon 100 into 100 is equal to 26 into 100. This implies that 18 p is equal to 2600. Now we divide by 18 on both sides of the equation and we get 18 p upon 18 is equal to 2600 upon 18. This implies that p is equal to 144.4 so we say that Anna consumed 144.4 percent of RDI of iron. Thus we can say that 26 mg is 144.4 percent of the RDI that is 18 mg of iron which is the required answer. This completes our session hope you enjoyed this session.
