(B) 97%
(D) 10 -4%
(C) 11%​

Answer 1

Answer: 9.1%

Step-by-step explanation:

2003 price is 100.

10% increase is 10/100 * 100 = 10.

2004 price = 100 + 10 = 110.

2004 price - 2003 price %

= ( 110 - 100 / 110 ) * 100

= ( 10 / 110 ) * 100

= ( 1/11 ) * 100

= 100/11

= 9.1%

Answer 2

By 9.09% its price in 2003 less than that in2004.

Given: In 2004, the price of a shampoo bottle increased by 10% concerning that in 2003.

To find: We have to find by what

percentage is its price in 2003 less than that in

2004.

Solution:

Let the price of the product be 100 in 2003.

In 2004, the price of a shampoo bottle increased by 10% concerning that in 2003.

Thus, the price of the product in 2004 is 110.

Now the price in 2003 less than that in

2004 is given as-

$\frac{110 - 100}{110} \times 100 \\ \frac{10}{110} \times 100 = 9.09\%$

By 9.09% its price in 2003 less than that in 2004.
