Answer:

y = 541

Step-by-step explanation:

The mean is calculated as

mean = $\frac{sum}{count}$

Mean of set A = $\frac{281+268+225+290}{4}$ = $\frac{1064}{4}$ = 266

ratio between means = 7 : 12, then

mean of set B = $\frac{12}{7}$ × 266 = 456 , thus

$\frac{392+512+413+422+y}{5}$ = 456 ( multiply both sides by 5 )

1739 + y = 2280 ( subtract 1739 from both sides )

y = 541
