The average weight of apples in a basket is 50 kg. 6 more apples with the average weight of 60 kg are added in the basket. If the average weight of the basket is increased by 5 kg, then find the number of apples in the basket originally.
Answer & explanation
Correct answer: option 2
Let's assume total number of apple in basket= n
New Total weight = Old Total weight + Added weight
55 x (n+6) = 60 x 6 + 50n
5n = 30
n = 6
