Answer 1

Answer:

40 girls

Step-by-step explanation:

Let K denote the Kamla , V denote the Veena and g's denote the other girls then sequence will be following

g,g,g,g,g,g,g,g,K,g,g,........,g,g,V,g,g,g,g,g,g,g,g,g,g,g,g,g,g,g

Now interchanging the K's and V's position we get

g,g,g,g,g,g,g,g,V,g,g,........,g,g,K,g,g,g,g,g,g,g,g,g,g,g,g,g,g,g

NOW if new position of K is at 25 place from left then

Total number number of girls = 25 + 15 = 40

So there are 40 girls altogether
