It can be seen that the ratios, AC/ PR and AB/ PQ are equal. So, we can assume it to be equal to a real number. This is a simple method of solving questions. Whenever two ratios are equal, for calculation purposes, we can assume both to be equal to a real number k. That is the reaon whey we have taken k here also.
