 Hello and welcome to the session. In this session we will discuss the following question and the question says, find the value of P in 3P is equal to x plus y plus RT when x is equal to 1, y is equal to 3, r is equal to 0.05 and T is equal to 400. Let's start the solution now. We are given 3P is equal to x plus y plus RT. Substitute the values of x, y, r and T in the other formula. We are given in the question that x is equal to 1, y is equal to 3, r is equal to 0.05 and T is equal to 400. So the given formula becomes 3P is equal to x which is equal to 1 plus y which is equal to 3 P plus r into T which is equal to 0.05 into 400. So this implies 3P is equal to 1 plus 3 plus 20 which implies 3P is equal to 24 which means P is equal to 24 by 3. Therefore the answer is P is equal to 8. With this we end our session. Hope you enjoyed the session.
