Question

The num of biscuits in each packet is equal to num of packets num of packets of biscuits in each box is equal to num of boxes If there is 3375 biscuits in all, then how many biscuits are in each packet

Answer 1

let say there are x biscuits in each packets

then number of packets of biscuits in each box= number of biscuits in each packet = x

number of boxes = number of the biscuit packets in each box = x

hence number of boxes = x

number of biscuit packets in x boxes = x *x = x^2

number of biscuits in x^2 biscuit packets = x^2*x = x^3

number of biscuits = 3375

x^3 = 3375

x^3 = 15^3

x = 15

so there are 15 biscuits in each packet.
