Question

দুটি ঘোড়ার দাম ২১০০০ টাকা । বাদামি রঙের ঘোড়াটির দাম কালো ঘোড়াটির দ্বিগুণ । ঘোড়া গুলির দাম কত?​

Answer 1

Step-by-step explanation:

let cost of black horse = x

cost of brown horse = 2x

x + 2x = 21000

3x = 21000

x = 7000

2x = 14000

cost of black horse = 7000

cost of brown horse = 14000

Answer 2

Given:-

• Cost of two horses = Rs. 21,000
• The cost of the brown horse is double than the cost of the Black horse.

To find:-

• The cost of the horses.

Solution :-

Let the cost of the black horse be x.

Therefore, The cost of the brown horse is 2x .

According to the question :-

$\sf\implies{x + 2x = 21000}$

$\sf\implies{3x = 21000}$

$\sf\implies{x = \frac{21000}{3} }$

$\sf\implies{x = 7000}$

Therefore,

The cost of the black horse = 7000

And the cost of the brown horse is (2x= 2× 7000)= 14000
