Jack’s first weight increased by 20% and then his new weight decreased by 25%. His final weight is what percent of his beginning
ElenaW [278]

Lets suppose his initial weight was 60 kilograms

A gain of 20%  would make his new eight  60 + 20*60/100

=  60 + 12

= 72 kg

he lost 25% of this:-

= 72 -   25 * 72/100 =  54 kg

This = (54/60) * 100  = 90% of his beginning weight  Answer

How many non-square numbers lie between the 215to the power of 2 and 216 to the power of 2
Vaselesa [24]

There are 430 non square numbers that lie between 215^{2} and 216^{2}.

Given two numbers 215^{2} and 216^{2} and we are require to find non square numbers that lie between them.

Numbers can be consecutive numbers or non consecutive numbers. In our question we will find the consecutive numbers.

Square numbers are those numbers whos square is in a proper number means decimal should not be there.

First number=215^{2}

Second number=216^{2}

First we have to find the exact value of numbers by finding the square of these numbers.

First number=215*215=46225

Second number=216*216=46656

Numbers that  lie between them=(46656-46225)-1

=431-1

=430

Hence 430 numbers lie between 215^{2} and 216^{2}.
