Question

Rani had a bag of 5kg bord seed. If she puts 425 g bird seed in the bird seeder everyday, how much is she left with it by end of a days?

Answer 1

Bord seed at end of days is 4575g, 4150g, 3725g ,……., 325g

Solution:

Given, Rani had a bag of 5kg bord seed.  

She puts 425 g bird seed in the bird seeder everyday.  

We have to find how much is she left with it by end of a days?

Now, let us convert kilo grams into grams → 5kg = 5 x 1000 = 5000 grams.

Now, after end of first day, bord seed left = 5000 – 425 = 4575g

After second day, bord seed left = 4575 – 425 = 4150g.

After third day, bord seed left = 4150 – 425 = 3725g.

And so on…

This forms an A.P where a= 4575, d = 425.

Now, after 11 days, $t_{11}$ = a + (11 – 1)d = 4575 – 10 x 425 =  4575 – 4250 = 325.

Here after, she can’t put 425 in bird seeder.

Hence, bord seed at end of days is 4575g, 4150g, 3725g,……., 325g.
