Ms. Agrawal has just sufficient amount of Rs.800 to purchase it at universal Shoppe Hazratganz. What is the amount that Ms. Agrawal has less than the required amount to purchase it at universal soppe Bhootnath ?
Correct Option: B
Let markup price be y. Cost price (CP) = 20 % discount on MP = 0.8y = 800 ⇒ y= Rs.1000 MP
SP at Hazratganz = Rs. 800 SP at Bhootnath = 1000 X 0.85 = 850
So, she requires Rs. 50 more to purchase the same calculator at Bhootnath.
