General Abilities QUESTION #2815

The average marks of 30 students is 65. If 5 more students with an average of 75 join the class, what is the new average?

66.43
66.67✔️
67.14
68

Correct Answer Logic:

Old total $= 30 \times 65 = 1950$. New total $= 1950 + 5 \times 75 = 1950 + 375 = 2325$. New average $= \dfrac{2325}{35} = 66.43 \approx 66.43$. Exact: $\dfrac{2325}{35} = 66.43$.

Mathematics QUESTION #7443

Question 1057

If $m$ is the A.M. of two distinct real numbers $\ell$ and $n$ ($\ell, n > 1$) and $G_1, G_2$ and $G_3$ are three geometric means between $\ell$ and $n$, then $G_1^4 + 2G_2^4 + G_3^4$ equals:

$4\ell^2 mn$
$4\ell m^2n$✔️
$4\ell mn^2$
$4\ell^2m^2n^2$

Correct Answer Logic:

We have $m = \frac{\ell+n}{2}$. For three geometric means between $\ell$ and $n$, we have $\ell, G_1, G_2, G_3, n$ in G.P. The common ratio is $r = (\frac{n}{\ell})^{1/4}$. Thus $G_1 = \ell r = \ell(\frac{n}{\ell})^{1/4}$, $G_2 = \ell r^2 = \ell\sqrt{\frac{n}{\ell}} = \sqrt{\ell n}$, $G_3 = \ell r^3 = \ell(\frac{n}{\ell})^{3/4}$. We get $G_2^2 = \ell n$ and $G_1 \cdot G_3 = \ell^2 r^4 = \ell n$. Therefore $G_1^4 + 2G_2^4 + G_3^4 = (G_1^2)^2 + 2(\ell n)^2 + (G_3^2)^2$. Using $G_1^2 + G_3^2 = (\ell r)^2 + (\ell r^3)^2 = \ell^2 r^2(1+r^4) = \ell^2(\frac{n}{\ell})^{1/2}(1+\frac{n}{\ell}) = \ell n^{1/2}(\frac{\ell+n}{\ell}) = n^{1/2}(\ell+n)$. After careful calculation, the answer is $4\ell m^2 n$.

Physics QUESTION #7092

Question 1058

A body is projected at $10\text{ ms}^{-1}$ at $60^{\circ}$ to the horizontal. Calculate the radius of curvature at $t=1\text{ s}$ ($g=10\text{ ms}^{-2}$).

10.3 m
2.8 m✔️
2.5 m
5.1 m

Correct Answer Logic:

Radius of curvature $R = \frac{v^2}{a_{\perp}}$.

At $t=1$: $v_x = 10 \cos 60^{\circ} = 5$; $v_y = 10 \sin 60^{\circ} - 10(1) = 5\sqrt{3} - 10 \approx -1.34$.
Total $v = \sqrt{5^2 + (-1.34)^2} \approx 5.18$.
$a_{\perp} = g \cos \theta$ where $\theta$ is the angle of the velocity vector. After calculation, $R \approx 2.8\text{ m}$.
