Answer» Correct Answer - Option 2 : 55% GIVEN: In a certain store, the profit is 210% of the cost. CONCEPT: Basic concept of Profit and Loss. FORMULA USED: Profit on the selling price = [(SP – CP)/SP] × 100 CALCULATION: Let Cost price = Rs. 100 Then, Profit = Rs. 210, So, Selling price = Rs. 310 New CP = 140% of Rs. 100 = Rs. 140 New SP = Rs. 310 Hence, Profit = Rs. (310 – 140) = Rs. 170 ∴ Required percentage = (170/310) × 100 = 54.83 = 55% (Approx.)

Answer» Correct Answer - Option 2 : 55%

GIVEN:

In a certain store, the profit is 210% of the cost.

CONCEPT:
Basic concept of Profit and Loss.

FORMULA USED:

Profit on the selling price = [(SP – CP)/SP] × 100

CALCULATION:

Let Cost price = Rs. 100

Then, Profit = Rs. 210,

So,

Selling price = Rs. 310

New CP = 140% of Rs. 100 = Rs. 140

New SP = Rs. 310

Hence,

Profit = Rs. (310 – 140) = Rs. 170

∴ Required percentage = (170/310) × 100 = 54.83 = 55% (Approx.)
