Question

The cost of 8 chairs is ₹ 1240. What will be the cost of 12 such chairs ?​

Answer 1

Answer:

Given cost of 8 chairs = Rs. 1240

Cost of 1 chair = Cost of 8 chairs / 8

⇒ Rs. 1240 / 8

⇒ Rs. 155

Now that we have found out the cost of 1 chair using the unitary method , we can now find the cost of 12 such chairs

⇒ Cost of 12 chairs = Cost of one chair x 12

⇒ Rs. 155 x 12

⇒ Rs. 1860

∴ Cost of 12 chairs = Rs. 1860

Hope it helped you guys!
