Question
The average weight of 5 students in a class is 25.8kg.
When a new student joins them, the average weight increases by 3.9kg. Then what will be the approximate weight of the new student?Solution
ATQ, we can say that  Weight of new student =  6(25.8 + 3.9) - 5 x 25.8  6 x 29.7 - 129  178.2 - 129  Hence, the required weight for new student is 49.2kg or 49 kg ans.
How many such pairs of letter are there in the word TELEPHONE, each of which has as many letters between them in the word as in the English alphabet?
