The marked price of a cooker is same at four shops I, II, III and IV. Shop I allows two successive discounts of 66% and 88%, shop II allows successive discounts of 78% and 70%, shop III allows successive discounts of 89% and 35% and shop IV allows successive discounts of 27%, 65% and 59% on the marked price of the cooker. Which shop is selling the cooker at the lowest price?

This question was previously asked in
RRB Group D 2025 Question Paper (9-Aug-2026) (Shift 1)
The correct answer is

I

Remaining price fraction after successive discounts \(d_1\%,d_2\%\) is \((1-d_1/100)(1-d_2/100)\).

Shop I: \(0.34 \times 0.12 = 0.0408\) (4.08%). Shop II: \(0.22 \times 0.30 = 0.066\) (6.6%). Shop III: \(0.11 \times 0.65 = 0.0715\) (7.15%). Shop IV: \(0.73 \times 0.35 \times 0.41 \approx 0.1048\) (10.48%).

Shop I leaves the smallest fraction of the marked price, so it sells at the lowest price.

Hence, this is the correct answer.(Shop I) is correct.
