Q. If the average mark of 15 students is 60 and the average mark of another 10 students is 70 , then find the average mark of 25 students. The following are the steps involved in solving the above problem. Arrange them in sequential order. (A) Average marks of 25 students $=\frac{1600}{25}=64$ (B) The total marks of 15 students $=15 \times 60=900$ The total marks of 10 students $=10 \times 70=700$ (C) The total marks of 25 students $=900+700=1600$

Solution:

$BCA$ is the required sequential order.
