There are two numbers such that the first number is 5 times of the second number. If the difference between the first and the second numbers is 120, then what is the average of these two numbers?
Answer & explanation
Correct answer: option 1
Let second number = A
Then First number = 5A
ATQ ,
5A - A = 120
4A = 120
A = 30
Sum of these two numbers = 6A = 6 × 30 = 180 kg
Average = \(\frac{180}{2}\) = 90 kg
