Answer 2

${\huge{\pink{\star{\mathcal{\green{An}{\blue{ws}{\red{er}}}}}}}}$

Let there be 'x' terms in the data ..

If each term is increased by 3 then ,

$\pink{new \: average} \: = \frac{old \: average \times x \: + 3 \times x }{x} \\ \\ \implies \: x( \frac{old \: average \: + 3}{x} ) \\ \\ \implies \: \green{old \: average} \: + \blue{3}$

So, OPTION C is correct

“increased by 3”
