QTY A

SInce change in BMI increased by 1

Therefore change in weight =$$\frac{h^2}{703} * change in BMI$$

= $$\frac{74^2}{703}* 1$$

= $$\frac{5476}{703}$$

in QTY B

change in BMI increased by 1.2

Therefore change in weight =$$\frac{h^2}{703} * change in BMI$$

= $$\frac{65^2}{703}* 1.2$$

= $$\frac{5070}{703}$$

Therefore QTY A> QTY B (since denominator are same in both qty)
