If $4 \circledcirc 5 = 189$ and $10\circledcirc 8 =1512$ then $ 6\circledcirc9$  =


A) 945

B) 1148

C) 983

D) 764

Answer:

Option A

Explanation:

$4^{3} + 5^{3}$  $= 64+125$ $=189$

is $4\circledcirc5$

$10^{3} + 8^{3}$ $= 1000+512$ $= 1512$ $=10 \circledcirc 8$

Similarly $6\circledcirc9$ $=6^{3} + 9^{3}$ $= 216+729$ $=945$.
