Answer 1

সঠিক উত্তর হচ্ছে: 14

ব্যাখ্যা: Suppose those integers are A and B and A is greater than B. Then,as per first condition ,A2+B2=100……………Equation-1. Next,as per second condition,A2 - B2=28……..Equation-2. Now,On adding the Eqn.-1 &2,we get 2 x A2=128 Hence,A2=64,So A=8. Putting this value in Eqn-1,we get B2=100–64=36,So B=6. Hence,their sum is 8+6=14.
