hi 

try like this 

if(Days <= '10',

(sum( {$<[FY]={"=$(vCurrentFY)"}>} Sales1 )+sum( {$<[FY]={"=$(vCurrentFY)"}>} sales 2))/ Sum({$<[FY]={"=$(vCurrentFY)"}>} qty)

,

sum( {$<[FY]={"=$(vCurrentFY)"}>} Sales1 )/ Sum({$<[FY]={"=$(vCurrentFY)"}>} qty)

if both fields sales 1 and sales 2 are in the same table than you can also use 

if(Days <= '10',

(sum( {$<[FY]={"=$(vCurrentFY)"}>} Sales1+ sales 2))/ Sum({$<[FY]={"=$(vCurrentFY)"}>} qty)

,

sum( {$<[FY]={"=$(vCurrentFY)"}>} Sales1 )/ Sum({$<[FY]={"=$(vCurrentFY)"}>} qty)
