A.
25, 36
B.
25, 46
C.
35, 46
Answer
D.
None of these

Answer: Option C

Solution

Answer: Option C
Solution:
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
