Question:
Abida bought 100 pens at the rate of Rs 3.50 per pen and pays a sales tax of 4%. The total amount paid by Abida is ______.
Solution:
Rs.364

Rate of per pen = Rs.3.50
Cost of 100 pens = 100 × 3.50 = 350
Sales tax on pen = 4%
Total amount paid = 350 × (4/100) + 350
= 350 × 1/25 + 350
= 14 + 350
= 364
