A) 3572
B) 5723
C) 35721
D) 57321
Correct Answer: C
Solution :
\[\because \]30% of 200 + \[\sqrt{?}\]= 48% of \[550-10%\]of 50 \[\therefore \]\[\sqrt{?}=48%\] of \[550-10%\] of \[150-30%\]of 200 \[=\frac{550\times 48}{100}-\frac{150\times 10}{100}-\frac{200\times 100}{100}\] \[=264-15-60\] \[=264-75=189\] So, \[?={{(189)}^{2}}=35721\]You need to login to perform this action.
