 Hello and welcome to the session. In this session we discussed the following question which says if 12, 24 and x are in continual proportion, find the value of x. If we have that a, b and c are in continual proportion, then a is to v is proportional to b is to c. And then the product of extremes that is a multiplied by c is equal to the product of means which is b multiplied by b equal to b square. That is we have b square is equal to ac. This is the key idea for this question. Let's move on to the solution now. It's given that 12, 24 and x are in continual proportion. Then we have 12 is to 24 is proportional to 24 is to x. And so the product of extremes that is 12 multiplied by x is equal to the product of means that is 24 multiplied by 24. Now this means x is equal to 24 into 24 upon 12. Now 12, 2 times is 24. So this is equal to 24 into 2 is equal to 48. That is we get x is equal to 48. So 48 is our final answer. This completes the session. Hope you have understood the solution for this question.
