Group B has seventeen painters between the ages of 10 and 20 and thirteen painters between the ages of 25 and 30.

Answer: 14500
Step-by-step explanation:
Let the price of the mobile phone before the GST was added be represented by x.
Therefore,
x + (12% × x) = 16240
x + 0.12x = 16240
1.12x = 16240
x = 16240/1.12
x = 14500
The price of the mobile phone before the GST was added was 14500
