Question

if 15 children can finish painting the furniture in 25 days how long will 5 children take to paint the same furniture​

Answer 1

Given:

• 15 children can finish a painting in 25days.

To Find:

• The number of days taken by 5 children to complete the work.

Concept Used:

• If number of boys will increase then the number of days to complete the work will decrease .
• And if we decrease the number of boys then the number of days to complete the work will increase.
• Here boys and number of days to complete the work are inversely proportional to each other i.e. if one will increase then the other will decrease and vice- versa.

Answer:

Here its given that 15 children complete the work in 25 days .

So , 1 child will complete the work in 15×25 days.

(Boys decrease number of days to complete the work increase)

Hence 5 children will complete the work in $\sf{\dfrac{15\times25}{5}}$ = 75.

Hence 5 children will complete the work in 75 days.

Answer 2

Answer:

Given:

→ If 15 children can finish painting the furniture in 25 days.

Find:

→ How long will 5 children take to paint the same furniture.

Calculations:

→ 15 childrens = 25 days.

→ If we multiply the number of students with the number of days it took to paint and then with that answer if we divide the number of children's which need to find the number of days they take to paint the same drawings, We get our required answer.

→ $\sf{\dfrac{15 \times 25}{5}}$

→ $\sf{\dfrac{375}{5}}$

→ ${\sf{\pink{\boxed{\boxed{\boxed{\sf{75 \: Days}}}}}}}$

Therefore, 75 days is the required time to complete the same paining by 5 childrens.
