Solution:

Sushma sold her watch for ₹3320 at a gain of ₹320.

For earning a gain of 10% she should have sold the watch for ₹3300.

We have to determine if the given statement is true or false.

According to the question,

SP = ₹3320

Profit = ₹320

We know, Profit = SP - CP

320 = 3320 - CP

CP = 3320 - 320

CP = ₹3000

Now, Profit% = 10%

We know, Profit% = Profit/CP × 100

10 = Profit/3000 × 100

10 = Profit/30

Profit = 10 × 30

Profit = ₹300

So, SP = Profit + CP

= 300 + 3000

= ₹3300

Therefore, SP = ₹3300.
