From: This question came in UPSC Final Exams held in Dec 2013.
You will be glad to note that only Gaurav Agarwal
(IAS Topper) could solve it.
Here are some answers;
1. Its written that *fill the boxes* not *fill all the three boxes*, if we need to fill all the 3 boxes using given series then the question may be wrong or just add O in third box.
Like this; 15+15+=30
Or 15+15+0=30
2. There is written that u can repeat the numbers so repeat it like below
(1+3)+(5+7)+(7+7)=30
