Question

Two numbers are less than a third number by 30% and 37%respectively how much percentage is the second number less than the first

Answer 1

Step-by-step explanation:

let third no. be x

then, second no =x-37%=x-37x/100 =63x/100

first no.=x-30%=x-30x/100 =70x/100

So,the second no. is less than the first no. by=>{(70x/100)-(63x/100)}/70x/100×100

=(30x/100)/70x/100×100

=3/7×100

=300x7

=42%<approx>
