2) If three metallic spheres of radii $6$ cms, $8$ cms and $10$ cms are melted to from a single sphere, the diameter of the new sphere will be:

3) Sixty men can build a wall in $40$ days, but though they begin the work together, $5$ men quit every ten days. The time needed to build the wall is:

4) Shyam is travelling on his cycle and has calculated to reach point 'A' at $2$ PM If he travels at $10$ kmph. he will reach there at $12$ noon if he travels at $15$ kmph. At what speed must he travel to reach point 'A' at $1$ PM:

5) An aeroplane travelling at $700$ kmph in level flight drops a bomb from a height of $1000$ metres on a target. The time taken from releasing the bomb to hitting the target is nearest to the figure:

6) Suppose students $=100$

$10×95=950\\
20×90=1800$

$950+1800+70x=80×100\\
x=75$

3) Total man days $=2400$

$60×10+55×10+50×10+45×10=2100$ man days
$\dfrac{300}{40}=7.5$ days

Total days $=10+10+10+10+7.5=47.5$ days

1) Volume, V $=\dfrac{22}{7}×12×12\left(\dfrac{4}{3}×12×\dfrac{1}{2}+h\right)=3312×\dfrac{22}{7}$
$12×12\left(\dfrac{4}{3}×12×\dfrac{1}{2}+h\right)=3312\\
\dfrac{4}{3}×12×\dfrac{1}{2}+h=23\\
8+h=23\\
h=23-8=15\text{ m}$

we will have to take up physics formulae for 5th one
$s=ut+0.5at^2$

here $s=1000$
$u=0$ (initial speed)
$a=g=9.8$ m/s²

So time can be calculated as $14.14$ sec

Answer for Q2:

If three metallic spheres melted down and formed a new sphere, volume of all three sphere will be equivalent to the volume of new sphere and final equation will be
$(r_1)^3+(r_2)^3+(r_3)^3=R^3$

here,
$6^3+8^3+10^3=R^3\\
\Rightarrow 216+512+1000=R^3\\
\Rightarrow R=1728^{1/3}\\
\Rightarrow R=12\text{ cm}$

Hence, diameter of the new sphere will be $(2R)$
i.e $24$ cm.

4. Since distance is same,
$s_1×t_1=s_2×t_2\quad$($s_1=10$ kmph, $s_2=15$ kmph)
$10(14-t)=15(12-t)\quad$ ($2$ o'clock on $24$ hrs clock is $14,$ while $12$ is $12$)
$140-10t=180-15t\quad$ ($t$ is the start time)
$5t=40$
$t=8$ hrs, means he had started journey at $8$ am

$d=s_1(14-t)\\
d=10(14-8)\\
d=60\text{ km}$

Time to reach destination $=13-8=5$ hrs
Speed $=\dfrac{d}{t}=\dfrac{60}{5}=12$ kmph
