Question

1. I made a square cardboard box. which has many square cells. Each row cells has as many as
there are number of rows. My brother kept one 5 rupee, one two rupee and a one rupee coin
in each cell. If total money kept is Rs 1152, then let's find how many cells are there in each
row of my card board box.


2. today is children's day. Few of us distributed toffee amd biscuit among the other students of school. But 800 toffees were left. so each took twice the number of toffees as we are I number. let's calculate among how many of us those 800 toffees were divided.

Answer 1

Step-by-step explanation:

1.) number of cells in a row = number of rows

Amount contained in one cell= 5 rupees + 2 rupees + 1 rupee = ₹8

Let the number of cells be x

Therefore, 8x = ₹1152

x = 1152/ 8

x = 144 = number of cells.

number of cells in a row =

$\sqrt{144 } \\ = 12$

Therfore there are 12 cells and 12 rows

2) Number of toffees left = 800

Let number of children = x

Therefore, number of toffees each took = 2x

:. x*2x= 800

2x²= 800

x²= 800/2

× = √400

x = 20

:. number of sgudent among which the toffees was distributed = 20.

HOPE THAT HELPED!!

Answer 2

Answer:

1.12

2.20

Step-by-step explanation:

1. 1152÷(5+2+1)

=144

the root of (144) = (12×12)=12

there are 12 cells in each card board of my box.

2. the root of (800)=(2×2×2×5)=40

the number of students who got one candy is 40.

so, the number of students who got twice candy is (800÷40)=20 students
