Step-by-step explanation:

What should come in place question mark (?) following simplification problem?

14.2% of 11000 + 15.6% of ? = 3590

Let say  1000X should come in place of ?

14.2% of 11000  + 15.6% of 1000X = 3590

=> (14.2/100)*11000  + (15.6/100)*1000X = 3590

=>  1562 +  156X = 3590

=> 156X = 3590 - 1562

=> 156X = 2028

=> X = 2028/156

=> X = 13

1000X = 13000

13000 should come in place of ?
