A) 938036
B) 920051
C) 852016
D) 732105
E) 658036
Correct Answer: A
Solution :
\[2462.92\times 390.06-17651.201=?+\] \[4883.001\] or,\[\approx 2463\times 390-17651-4883\] \[=960570-22534=938036\] \[\sqrt{10200}\times \sqrt{9215}-{{(43.96)}^{2}}=?+{{(64.105)}^{2}}\] or,\[?\approx \sqrt{10201}\times \sqrt{9216}-{{(44)}^{2}}-{{(64)}^{2}}\] \[=101\times 96-1936-4096\] \[=9696-6032=3664\]
