@@bhaskarchhetri6821
average age of 40 students is 15 year. [given]
after including 10 new students there average age increase by 0.2 year.
therefore,
sum = average age x total no. of student
600 = 15 x 40 ..equation1
**after adding 10 new students**
sum = average age of total student x total no. of students
760 = (15+0.2) x 50 ..equation2
hence, the total age of 10 new students is = 160 [760-600]

Sir -ve sign kese Aya replacement wale questions me
If average increases to +ve sign agar av decreases to - ve sign
Bcz initial av. Age 28 thi but final av. age 27 h, to it means av. Age decrease hui h to isi liye sign -ve h.
Many many thanks

Sir please make a video of simplification of class
Sir car weight wale question mein difference krk negative ka sign q ni liya or next question mein servant wale question mein plus or minse (-) sign ko q consider kiya hai???? Kon se question mein krna hai or Nhi krna ye kese pta chlega
What didn't you taken -ve sign in previous question
coz - - + hota hai at last might be that y??/…… I also get confused
Coz, in that question 28 was subtracted from 27 (27-28=-1)
But in this question 40 is subtracted from 41 (41-40=1)
That's why it is positive
@@pragyaregmi8462 becoz on that question they mention the word Reduces by 1 year that's why
