Download Solution PDFGiven:
x = 0.25 and y = 0.16
Calculation:
\(\frac{y}{x}+\sqrt{x} \sqrt{y}-x y\)
⇒ \(\frac{0.16}{0.25} + \sqrt0.25\sqrt0.16 - 0.25 \times 0.16\)
⇒ \(\frac{16}{25} + 0.5\times 0.4 - 0.04\)
⇒ \(\frac{16}{25} +0.20 - 0.04\)
⇒ \(\frac{16}{25} \) + 0.16
⇒ 20/25
⇒ 0.8
∴ The correct answer is 0.8
