Which one will replace the question mark ?
Answer: Option D
Explanation:
Sum of numbers in lower half of the circle = 11 + 9 + 3 + 7 = 30
Sum of numbers in upper half of the circle = ? + 4 + 5 + 6 = ? + 15
Upper half = Lower half
30 = ? + 15
? = 30 - 15
? = 15.
Threfore, 15 is the answer.
Answer: Option B
915 - 364 = 551
and 789 - 543 = 246
Similarly, 863 - 241 = 622.
Answer: Option C
Answer: Option A
(12)2 - (8)2 = 80
and (16)2 - (7)2 = 207
Therefore (25)2 - (21)2 = 184.
(2)3 + (1)3 + (3)3 = 36
and (0)3 + (4)3 + (3)3 = 91
Therefore, (4)3 + (2)3 + (1)3 = 73.
