Question

Raman purchased insecticides for his farm at Rs.23,600 including GST.if the cost price of the insecticides wasRs.20,000,how much GST (in%)has he paid

Answer 1

Let GST paid be x %
then,

$\frac{100 + x}{100} \times 20000 = 23600 \\ \frac{100 + x}{1} \times 200 = 23600 \\ 100 + x = \frac{23600}{200} \\ 100 + x = 118 \\ x = 118 - 100 \\ x = 18\%$

He paid 18% GST.
