0.64 kg. was repalced by a new mango. What is the weight of the new mango ?
a) 0.5 kg b) 0.46 kg c) 0.57 kg d) 0.59 kg.​

Answer 1

Answer:

0.46kg

Step-by-step explanation:

let the first average=x

so total mass ,m1=6x

new average =x-0.03

so total mass,m2=6*(x-0.03)

                            =6x-0.18

decrease in total weight=0.18

the weight of mango taken out =0.64

then weight of new mango =0.64-0.18

                                             =0.46kg
