So 12 people can do in ____ days?

______________________________________

$\huge\underline{\underline{\ Answer}}$

Here,in this case,

Number of people is inversely proportional to number of days.

As number of people increase days will decrease.

you can easily visualise this..

If number of people is doubled

then,

number of days will be half

So 12 people can do the same work in 8/2 days

i. e 4 days..

Answer 2

AnswEr :

• 6 People work in 8 Days
• 12 People will do that work in how many days?

M₁ = 6, D₁ = 8 and, M₂ = 12, D₂ = ?

• using the Formula Now :

⇒ M₁D₁ = M₂D₂

• Plugging the Values Now

⇒ 6 × 8 = 12 × D₂

⇒ ( 6 × 8 ) /12 = D₂

⇒ ( 1 × 8 ) /2 = D₂

⇒ D₂ = 4 Days.

∴ 12 People will finish the work in 4 Days.

_________________________________

• Shortcut Trick :

In first Part of Question 6 People are Doing work in 8 Days. Then in Second Part of Question People are Doubled so, Days will be half.

↦ 6 People = 8 Days

Doubling the People Means Half of Days.

↦ 12 People = 4 Days

∴ 12 People will finish the work in 4 Days.
