Step-by-step explanation:
Answer:
Given :-
25 men working 8 hours a day produce 200 toys in 10 days.
1000 toys will be produce by 100 men in 10 hours a day.
To Find :-
In how many days 1000 toys will be produce by 100 men, if they work 10 hours a day.
Solution :-
{\small{\bold{\purple{\underline{In\: the\: {1}^{{st}}\: case\: :-}}}}}
Inthe1
st
case:−
Given :
Total number of men = 25
Total number of toys = 200
Total time taken = 8 × 10 = 80 hours
{\small{\bold{\purple{\underline{In\: the\: {2}^{{nd}}\: case\: :-}}}}}
Inthe2
nd
case:−
Given :
Total number of men = 100
Total number of toys = 1000
Total time taken = 10D hours
Now, according to the question :
\begin{gathered} \implies \sf 25 \times 200 \times 80 =\: 100 \times 1000 \times 10D\\\end{gathered}
⟹25×200×80=100×1000×10D
\begin{gathered} \implies \sf 5000 \times 80 =\: 100000 \times 10D\\\end{gathered}
⟹5000×80=100000×10D
\implies \sf 400000 =\: 1000000D⟹400000=1000000D
\implies \sf \dfrac{40000\cancel{0}}{100000\cancel{0}} =\: D⟹
100000
0
40000

=D
\implies \sf \dfrac{4000\cancel{0}}{10000\cancel{0}} =\: D⟹
10000

4000

=D
\implies \sf \dfrac{400\cancel{0}}{1000\cancel{0}} =\: D⟹
1000

=D
\implies \sf \dfrac{40\cancel{0}}{100\cancel{0}} =\: D⟹

\implies \sf \dfrac{4\cancel{0}}{10\cancel{0}} =\: D⟹
10

\implies \sf \dfrac{\cancel{4}}{\cancel{10}} =\: D⟹
10

=D
\implies \sf \dfrac{2}{5} =\: D⟹

=D
\implies \sf\bold{\purple{D =\: \dfrac{2}{5}\: days}}⟹D=

days
Hence, the required day is :
\dashrightarrow \sf Total\: time\: taken =\: {\cancel{10}} \times \dfrac{2}{\cancel{5}}⇢Totaltimetaken=
10
×
5
2
\dashrightarrow \sf Total\: time\: taken =\: 2 \times 2⇢Totaltimetaken=2×2
\dashrightarrow \sf\bold{\red{Total\: time\: taken\: =\: 4\: days}}⇢Totaltimetaken=4days
\therefore∴ In 2/5 days 1000 toys will be produce by 100 men, if they work 10 hours a day.
