Correct Answer: 1200

Solution : Given: The total population of state B is 3000.
Population under the poverty line in state B = 3000 × $\frac{60}{100}$ = 1800
So, the required number of girls = 1800 × $\frac{4}{2+4}$ = 1200
Hence, the correct answer is 1200.

Correct Answer: $x^{2}-1$

Solution : Given: $\frac{1}{\operatorname{cosec}^{2}51°}+\sin^{2}39°+\tan^{2}51°-\frac{1}{\sin^{2}51°\sec^{2}39°}$
= ${\sin^{2}51°}+\sin^2(90°-51°)+\tan^{2}51°-\frac{\cos^{2}39°}{\sin^{2}(90°-39°)}$
= ${\sin^{2}51°}+\cos^251°+\tan^{2}51°-\frac{\cos^{2}39°}{\cos^{2}39°}$
= $1+\tan^251°-1$
= $1+\cot^239°-1$ $[\because \tan^251°=\cot^239°]$
= $\operatorname{cosec}^239°-1 $
= $x^{2}-1$
Hence, the correct answer is $x^{2}-1$.

Correct Answer: 4I32MG1O

Solution : Given:
COATED is written as X41G2W.

Code vowels as A→1; E→2; I→3; O→4; U→5 and consonants are coded with opposite letters of COATED, to obtain the required code –
C→X; O→4; A→1; T→G; E→2; D→X
Thus, COATED is coded as X41G2DX.
Similarly, follow the same
