Can someone help me with this question please.

y = 541

Step-by-step explanation:

The mean is calculated as

mean =

Mean of set A = = = 266

ratio between means = 7 : 12, then

mean of set B = × 266 = 456 , thus

= 456 ( multiply both sides by 5 )

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

y = 541
