*Question 1*: If the mean of the given data is 250, then find the value of p.

*Solution*:

∑f_{i} = 41 + p and ∑f_{i}x_{i} = 9350 + 350p

9350 + 350p / 41 + p = 250

9350 + 350p = 10250 + 250p

100p = 900

p = 9

Mode

= I+(f_{1}−f_{o}2f_{1}−f_{o}−f_{2})×h

= 30 + 48 − 3296 − 32 − 30 × 10

= 34.71
