The change that the school girl will get based on the information is -18GP.
It should be noted that 100GP = 1GH
Therefore, GH 2.50 = 250GP
From the information, the school girl bought six pens at 24GP each four pencil at 25GP each and 3. erasers at 8Gp each.
Therefore, the amount left will be:
= 250 - (6 × 24) + (4 × 25) + (3 × 8)
= 250 - (144 + 100 + 24)
= 250 - 268
= -18
Therefore, the person won't have a change but will owe 18GP.
