Question

By what number should the given number be multiplied to increase the number by 50%

Answer 1

Let that number be x.

Let the number which we multiply to increase x to 50% be n.

According to the given condition,

xn=x+50x/100

xn=x(1+50/100)

n=1+50/10 [x and x will get cancelled]

n=1+1/2

n=2+1/2 [LCM =2]

n=3/2

So a given number should be multiplied by 3/2.
