Question

Of the leaves of a tree, one fourth fall in the first week of October, one third of the remainder in the next week and two fifth of those still remaining fall in the third week. There are then 1350 leaves left. How many were at first? ​

Answer 1

Answer:

let there be x leaves

x/4 leaves fall in the first month of October

leaves remaining = x -x/4

= 3x/4

in second week one third of the remainder fall

that's 1/3 x 3x/4= 3x /12 = x/4

leaves remaining in the third week

3x/4 - x/4 = 2x/4 = x/2

leaves falling in the third week = 2/5 x x/2

= x/5

but 1350 still remains

as per condition

x/4 + x/4 + x/5 + 1350 =x

2x/4 + x/5 +1350 = x

x/2 + x/5 +1350= x

7x /10 +1350=x

7x+13500 =10x

3x = 13500

x = 4500

there were 4500 leaves at first . plz mark brainliest
