Question : Directions: In this question, some equations are solved on the same basis as a certain system. On the same basis, find out the correct answer out of the four alternatives for the unsolved equation.
If 17 + 17 = 2895, 19 + 19 = 3615, then 23 + 23 = ?
Option 1: 5765
Option 2: 5295
Option 3: 2565
Option 4: 4005
Correct Answer: 5295
Solution :
Given:
17 + 17 = 2895; 19 + 19 = 3615
Like, 17 + 17 = 2895→17
2
= 289
Now, on adding 5 at the unit place the result will be 2895.
And, 19 + 19 = 3615→19
2
= 361
Now, on adding 5 at the unit place the result will be 3615.
Similarly, follow the same pattern for 23 + 23 = ?→23
2
= 529
Now, on adding 5 at the unit place the result will be 5295.
Hence, the second option is correct.
