Question

4. The price of a refrigerator has increased by 12%. 6 months back the price was Rs. 9600. What is the price now?

Answer 1

Old price was=₹ 9600
It increase by=12%
(For your understanding if old price was 100 and increase by 12 % then price will be=₹112)

So now a/q
$9600 + (9600 \times 12\%) \\ = 9600 + (9600 \times \frac{12}{100} ) \\ = 9600 + (96 \times 12) \\ = 9600 + 1152 \\ = rs \: 10752$
So price now=₹10752

Thanks
