Answer 1

$\huge{\underline{\mathtt{\red{S}\pink{O}\green{L}\blue{U}\purple{T}\orange{I}\pink{O}\red{N ᭄}}}}$

Here we can use direct formula,

$\implies\sf{3×Median−2×Mean=Mode}$

$\implies\sf{3×26−2×Mean=29}$

$\implies\sf{78−29=2×Mean}$

$\implies\sf{Mean= \frac{49}{2} }$

$\implies\sf{Mean=24.5}$

Answer 2

Answer:

Here we can use direct formula,

3×Median−2×Mean=Mode

3×26−2×Mean=29

78−29=2×Mean

Mean=
