Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. ₹3,150.

Let CP of B = a

⇒ CP of A = 120% of a

⇒ CP of A = 1800 × 10080100\over80

Now,

⇒ 1800 × 10080100\over80 = 120% of a

⇒ a = 1875 = CP of B

CP of A = 120100120\over100 × 1875 = ₹2250

Total CP = 2250 + 1875 = ₹4125

Total SP = 4125 × 120100120\over100 = ₹4950

SP of B = 4950 - 1800 = ₹3150
