(i) It is given that

M.P. of an article = ₹ 2250

Discount = 12 %

We know that

S.P. = [1 – d/100] of M.P.

Substituting the values

S.P. = [1 – 12/100] of ₹ 2250

By taking LCM

S.P. = (100 – 12)/100 × 2250

By further calculation

S.P. = 88/100 × 2250

So we get

S.P. = 88/4 × 90

S.P. = 22 × 90

S.P. = ₹ 1980

(ii) It is given that

S.P. = ₹ 1980

Profit = 10%

We know that

S.P. = [1 + P/100] of C.P.

Substituting the values

1980 = [1 + 10/100] of C.P.

By further calculation

1980 = 110/100 of C.P.

So we get

C.P. = 1980 × 100/100

C.P. = 18 × 100

C.P. = ₹ 1800

Therefore, the cost price is ₹ 1800.
