Correct Answer: 4 : 3

Solution : Using the alligation method, we get,

Required ratio = (Higher value – Mean value) : (Mean value – Lower value)
$\therefore$ Required ratio = (60 – 40) : (40 – 25) = 20 : 15 = 4 : 3
Hence, the correct answer

Correct Answer: $1$

Solution : Given:
$a=b^p,b=c^q,c=a^r$
$a=b^p$
⇒ $a=(c^q)^p$
⇒ $a=(a^r)^{pq}$
⇒ $a^1=(a)^{pqr}$
$\therefore pqr=1$
Hence, the correct answer is 1.

Correct Answer: –8

Solution : We have,
$x^4+x^2 y^2+y^4=21$ and,
$x^2+xy+y^2=3$ -----------------(i)
Use the identity,
$x^4+x^2 y^2+y^4=(x^2-x y+y^2)(x^2+x y+y^2)$
$⇒21=3(x^2-x y+y^2)$
$⇒x^2-x y+y^2=7$ ---------------------(ii)
From (i) and (ii),
$⇒2xy=-4$
$⇒4xy=-8$
Hence, the correct answer is –8.
