Solution

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.
