....15ो तोका मान ज्ञात कीजिए।​

Answer 1

Step-by-step explanation:

Let the fourth proportional to the numbers 3 5 and 12 be x. Then from the definition of the fourth proportional, we must have:

3: 4:: 12 : x or in terms of the fractions we can write;

3x= 5× 12. In other words, we have x = {5× 12}/3= 2715 Thus the correct option is 15
