Why you took 3 for multiplication? Can we take any other number?
Since the given options contains 6, 10, 4 and 8 in denominator
∴ we will multiply and divide the mean by 3, 5, 2 and 4 to make like fractions with the mean
but as we obtained the answer after multiplying with 3
Hence, there is no need to multiply with 5, 2 and 4
