Question

If 2 1/2% of the weight of table is 0.2 kg, then what will be 120% of it ?

Answer 1

let the weight of table be X.

2.5% of weight is .2kg.
so
2.5X/100 = 200gm
so
X= 200×100/2.5=8000gm

now 120% of 8000gm or 8kg will be

120×8/100= 9.6kg.

Another way to solve the question is :

now we know 2.5% weight of table is .2kg
then
120% will be :

weight of table= .2*120/2.5= 9.6
