Question

In Zedland, couriering a parcel costs (i) 3.25 zeds per kg and (ii) a fixed pick-up service charge of 5 zeds.
Shyleja sends some books weighing ‘w’ kg.
If Shyleja paid 57 zeds, the weight of her parcel was
a) 10.75 kg
b) 15 kg
c) 16 kg
d) 12.5 kg

Answer 1

Answer:

16 kgs

Step-by-step explanation:

Here, cost of a parcel per kg = 3.25 zeds

Fixed pick-up service charge = 5 zeds

Let the weight be w kgs.

Therefore, the equation is C = 3.25×w+5.

According to question,

Here, C = 57

So, 57 = 3.25×w+5

=> 3.25×w = 52

=> w = 52/3.25 = 52×4/13 = 16 kgs (1/3.25=4/13)
