उत्तर
This statement is False.
Explanation:
Given, C.P. = ₹ 2000 and profit % = 10%
We know that,
Profit % = `"Profit"/"C.P." xx 100%`
⇒ Profit % = `("S.P." - "C.P.")/"C.P." xx 100%` ...[∵ Profit = S.P. – C.P.]
⇒ `10 = ("S.P." - 2000)/2000 xx 100%`
⇒ `(10 xx 2000)/100` = S.P. – 2000
⇒ 200 = S.P. – 2000
∴ S.P. = ₹ 2200
Hence, the S.P. of chair is ₹ 2200.
