let no of boys in group is = x
then total sum = 30 * x
after joining one more boys with a weight of 35 kg the total sum is = 30x + 35
after joining the new student the weight will increase 1 kg
so total sum
30x + 35 = 31(x+1)
x = 4

Ans is 2(Prime numbers)

Sum of 5 consecutive nos is 35

so X + (X+1) + (X+2) + (X+3)+ (X+4) = 35

5X + 10 = 35

X = 5

So the 5 consecutive numbers are : 5, 6, 7, 8, 9

The Prime numbers are 5 and 7

X share is 10500
Y share is 13500
Z share is 16500

Initially, potatoes have 99% water by weight ; which means they have 1% solid non-water content.

1% of 100 kg = 1 kg

Now even when they dehydrate,this 1kg solid mass remains constant.

It is given that finally, 98% is water by weight , which implies that 2% is non-water solid.

This means 2% of total weight = 1 kg

Total weight *2/100 = 1 kg

Therefore, total weight finally = 50 kg.

Time =9 seconds

Speed =(60×518) m/sec=(503)m/sec

∴ Speed =DistanceTime

Length of the train (Distance) = (Speed × Time) = (503×9) m=150 m.

Joe is fencing in a square area of 576 square feet.
Fence posts, which are needed every three feet, cost 32.00 each.
The fencing cost 4.50 per foot. What is the total cost of the fencing materials?

Solution:-
Area of Square is 576 sq ft.
so, the length of side = root(576) = 24 ft

Since the fencing would be done on the perimeter, we would need that
formula is 4*side = 96 ft.

Number of Fence post needed = 96/3 = 32

1 Fence post cost = 32
32 Fence Post cost = 32 * 32 = 1024

Fencing cost = Perimeter * fencing cost = 96 * 4.5 = 432

Total Cost = 432 + 1024 = 1456

Let the person ate x banana on first day, so below is the equation for five days
X+x+6+x+12+x+18+x+24=100
So, he ate 8 banana first day
