prices are​

Answer 1

Answer:

Rs.24,000 and Rs.30,000

Step-by-step explanation:

Prices of X and Y are 4x and 5x

4x increased by 10%

So, (10% of 4x) + 4x

= 4.4x

5x increased by 6000

So, 5x+6000

The ratio of new 11:15

(4.4x) : (5x+6000) = 11:15

(4.4x)/(5x+6000) = 11/15

Cross multiplication

15 × (4.4x) = 11 × (5x+6000)

66x = 55x + 66000

11x = 66000

x = 6000.

The old prices are

4x = 4×6000 = 24000

5x = 5×6000 = 30000

So, the pre increased prices are Rs.24,000 and Rs.30,000
