Answer 1

Given :

• In a camp there is enough for 3300 men for 45 days.

• 15 more people join the camp after 3 days.

To find :

• How long the floor will last =?

Step-by-step explanation :

15 extra men join then total men = 3300 + 15 = 3315.

Let,after the joining of 15 men (after 3 days), It took x days to the floor will last.

According to the question :

➮ 3300 × 45 = 3300 × 3 + 3315 × x

➮ (3300 × 45) - (3300 × 3) = 3315x

➮ 3300(45 - 3) = 3315x

➮ 3300 × 42 = 3315x

➮ 138,600 = 3315x

➮ 138,600/3315 = x

➮ x = 41.80

Or, 42 (approx)

Therefore, the floor will last = 41.80 Or 42 days (approx) .

Answer 2

Correct Question

☛In a camp there is enough for 3300 men for 45 days how long the food will last 15 more people join the camp after 3 days.

➭ food available for 1 man in a camp = 3300×45= 148500 days

➭ food required after 15 men join the camp for 3 days = 3300× 3 =9900

Remaining food after 15 men join for 3 days

148500-9900= 138600

➦ 138600= d × 3315

_______________________________

Short cut method to calculate .

➭ 3300× 45 = 3300×3 + 3315 × d

➭ 148500= 9900 + 3315 × d

➭ 148500-9900=3315× d

➭ d = 138600/3315

➭d = 42 days.
