why don't you put reasoning and verbal ability questions. I like this page very much, because of aptitude questions. Why don't you put reasoning and verbal questions.

6) Suppose students $=100$
$10×95=950\\
20×90=1800$
$950+1800+70x=80×100\\
x=75$
$10×95=950\\
20×90=1800$
$950+1800+70x=80×100\\
x=75$

$d=(t-2)×15$
$t=6$ hrs
$d=60$
$60=5×s$
speed $=12$ km/hr
$d=(t-2)×15$
$t=6$ hrs
$d=60$
$60=5×s$

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
$60×10+55×10+50×10+45×10=2100$ man days
$\dfrac{300}{40}=7.5$ days
Total days $=10+10+10+10+7.5=47.5$ days

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

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
$s_1×t_1=s_2×t_2\quad$($s_1=10$ 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
