Let the fraction of beta anomer be x ,then fraction of alpha anomer will be 1-x as open chain fraction is very low so we can neglect it.
Specific rotation of only Beta anomer=+1000°
Specific rotation of only alpha anomer=+400°
Specific rotation of both alpha and beta form=880°
We can say that,
x(1000)+(1-x)400=880
x=0.8
So, the percentage of beta form will be 80%
