Question

Renu reduced her weight by 15℅.if now she weighs 52.7kg,what was her earlier weight.

Answer 1

Formula:

= > Original Weight = (Present Weight * 100)/(100 - reduced weight)

                                 = (52.7 * 100)/(100 - 15)

                                 = (5270)/85

                                 = 62.



Therefore her earlier weight = 62kgs.



Hope this helps!

Answer 2

$\textbf{Answer}$

Suppose that the earlier weight of Renu was x kg.

Since Renu reduced 15% of her earlier weight,her reduced weight is 52.7 kg.

=> x - 15% of x = 52.7

=> x - x(15/100) = 52.7

=> x - 3x/20 = 52.7

=> (20x - 3x)/20 = 52.7

=> 17x = 52.7 × 20

=> 17x = 1054

=> x = 1054/17

=> x = 62

$\textbf{So the earlier weight of Renu was 62 kg.}$
