Question

When Tim’s weight increased by 25%, he started working out and reduced his weight by 30%. If he now weighs 70 kg, what was his weight initially?

Answer 1

let his initial weight =x

weight increased by 25%, w

= (1+25%)*x

= 1.25x

weight reduces by 30%

= (1-30%)w

= (1-.3)×1.25x

=.7×1.25x

= 0.875x = 70

x = 70/0.875 = 80 kg
