The sum of the squares of two numbers is 3341 and the difference of their squares is 891. The numbers are :
A. 25, 36
B. 25, 46
C. 35, 46
D. None of these
Answer: Option C
Solution(By Examveda Team)
Let the numbers be x and y.Then,
x2 + y2 = 3341..... (i)
And,
x2 - y2 = 891..... (ii)
Adding (i) and (ii), we get :
2x2 = 4232
or x2 = 2116
or x = 46
Subtracting (ii) from (i), we get :
2y2 = 2450
or y2 = 1225
or y = 35
So, the numbers are 35 and 46
