 Hello and welcome to the session. In this session we will discuss the question which says that at the end of the day a pharmacist counted and found she has 3 more than 4x3 times as many prescriptions or antibiotics as she did for tranquilizers. She had 48 prescriptions for antibiotics, how many prescriptions did she have for tranquilizers. Now let us start with the solution of the given question. Now in the question it is given that a pharmacist has 3 more than 4x3 times as many prescriptions of antibiotics as she did for tranquilizers. Now let the number of prescriptions for antibiotics be x. Then according to the question the number of prescriptions for tranquilizers will be 3 more than 4x3 times as many prescriptions of antibiotics. Now here the number of prescriptions for antibiotics is x. So 4x3 times number of prescriptions for antibiotics will be 4 by 3 of x because the phrase times represents the operation of multiplication. So 4 by 3 times number of antibiotics is equal to 4 by 3 of x which can also be written as 4 by 3 into x. Now here the number of prescriptions for antibiotics is x. So 3 more than 4 by 3 times x will be equal to 3 plus 4 by 3 of x the phrase more than represents the operation of addition. So according to the question the number of prescriptions for tranquilizers is 3 more than 4 by 3 times as many prescriptions of antibiotics which means 3 plus 4 by 3 of x or we can write it as 3 plus 4 by 3 into x. Now the question is also given that number of prescriptions for antibiotics is 48. Now if number of prescriptions for antibiotics is 48 then let us find the number of prescriptions for tranquilizers. Now we know that number of prescriptions for tranquilizers is 3 plus 4 by 3 into x. Now here x is 48. So number of prescriptions for tranquilizers will be 3 plus 4 by 3 into 48. Now we know that 3 into 16 is 48. So this is equal to 3 plus 64 which is equal to 67. So from here you can see if number of prescriptions for antibiotics is 48 then number of prescriptions for tranquilizers is 67. So this is the solution of the given question and that's all for this session. Hope you all have enjoyed the session.
