a) a fortnight, b) a month, and c) a year? (Fortnight means $15$ days, $1$ month $=2$ fortnight)

Answer 1

Step 1: Calculating the quantity of hay eaten by the elephant in a fortnight.

Given: In one day elephant eats $=40$kg.

So, In a fortnight ( $15$ days ) elephant will eat $=40\times 15$

$=600$ kg

Step 2: Calculating the quantity of hay eaten by the elephant in a month.

In a month ( $30$ days ) elephant will eat $=40\times 30$

$=1200$ kg

Step 3: Calculating the quantity of hay eaten by the elephant in a year.

In a year ( $365$ days ) elephant will eat $=40\times 365$

$=14600$ kg

Hence, an elephant eats $600$ kg in a fortnight, $1200$ kg in a month and $14600$ kg in a year.
