Question

A milk boy sold Milk in packets of 250ml and 500ml. He sold 6L of milk 17 packests. How many packets of each type did he sell?

Answer 1

Answer: He sold ten 250 ml packets and seven 500 ml packets

Step-by-step explanation:

Let number of 250 ml packets = s

and number of 500 ml packets = l

Hence, 250s +500l = 6000

or, s + 2l = 24

and, s + l = 17

subtracting,

2l +s - s - l = 24 - 17

or, l = 7

hence, s = 10
