Question

please give the correct answer ASAP​

Answer 1

Answer:

We have 4N=449=12.25

The cumulative frequency just greater than 4N is 26 and the corresponding value of the variable is 61

∴Q1=Rs. 61

Middle Quartile (median): 

We have 2N=249=24.5

The cumulative frequency just greater than 2N is 26 and the corresponding value of the variable is 61

∴Q2=Rs. 61

Upper Quartile:

We have 43N=43×49=36.75

The cumulative frequency just greater than 43N is 41 and the corresponding value of the variable is 63

∴Q3=Rs. 63

∴2Q1+Q3=261+63=62
