Question

When numerator of number is increased by 200% and demoninator is incresed 400% and number become 1 1/20.Find number

Answer 1

Let numerator be x and denominator be y

Numerator increased by 200% would mean x +2x= 3x .

Denominator increased by 300% would mean y+3y= 4y .

So 3x/4y = 11/12

x/y = 44/36 => x/y= 11/9

So your answer comes out to be 11/9

You can cross check by adding 200% of your numerator to 11 (11+22=33)

And adding 300% of denominator to 9 (9 +27= 36)

Solving 33/36 gives you 11/12 .
