सत्य या असत्य

उत्तर

This statement is True.

Explanation:

S.P. of a watch = ₹ 3320

Gain = ₹ 320

∴ C.P. of the watch = ₹ (3320 – 320) = ₹ 3000

Required gain % = 10

S.P. = `((100 + "Gain"%)/100) xx C.P.`

= `((100 + 10)/100) xx 3000`

= `110/100 xx 3000`

= ₹ 3300

So, for earning again of 10% Sushma should have sold the watch for ₹ 3300.
