Solution :
Given:
A merchant marked the cloth at Rs. 50 per metre. He offers two successive discounts of 15% and 20%.
Here, two successive discounts are 15% and 20%.
So, the net price after successive discounts
= $50×(\frac{100\:–\:15}{100})×(\frac{100\:–\:20}{100})$
= $50×\frac{85}{100}×\frac{80}{100}$
= Rs. 34
Hence, the correct answer is Rs. 34.00.
