Correct Answer: INR 50.12


Solution : First discount = 35% of 700
Successive discounts = 18% and 12%
Effective discount = $18+12-\frac{18×12}{100}= 30-2.16 = 27.84$%
Second discount = 27.84% of 700
Required difference = (35 – 27.84)% of 700
= 7.16% of 700
= 0.0716 × 700
= 50.12
Hence, the correct answer is INR 50.12.
