In a party there are 50 persons . If every person shake their own hands with every other . Then find how many hands were shaked in the party..

Answer»

Hola!
It is kinda Brain Teaser... let's try to find out the answer :)

ATQ,

→ The first person shakes hands with all 49 others.

→ The SECOND person only has to shake hands with 48 others, as he’s already shaken hands with the first person.

→ The third person shakes hands with seven others.

n' the cycle continues till it REACHES the last person!

Applying logic :

49 + 48 + 47 + ... + 1 = 1225

Hence,
In total 1225 hands were shaken in the party.

Hope it helps! :D

five cubes of dimension 2cm melted into a cuboid of length 5cm breadth 2cm find the height of a cuboid

Answer» HEY friend...!! here's your answer
__________________________


Dimension of each cube = 2 cm
Dimension of New cuboid = 5 × 2

we need to find the height of cuboid,


Volume of cube = Volume of cuboid
a^3 = LENGTH × Breadth × Height

(2)^3 = 5 × 2 × height
8 = 10 × height
height = 8/10

So that the height of cuboid is 4/5 cm

If you subtract 1.2 from a number and multiply the result by 1.2 you get 1.8 what is the number

Answer» LET the no. be X

ATQ,
(x-1.2)×1.2 =1.8
x-1.2 =1.8/1.2
x-1.2 =(18/10)÷(12/10)
x -1.2 =3/2
x-(12/10) =3/2
x=(3/2)+(12/10)
x=(15+12)/10
x=2.7


Thus,
The no. is 2.7...
