Question

If the cost of one article is ₹1800, then what is the cost of 20 such articles?

• A. ₹36000
• B. ₹1820
• C. ₹ 1780
• D. ₹ 3600

Answer 1

The correct option is A

₹36000

Cost of one article = ₹ 1800

Hence, the cost of 20 such articles is given by

$₹1800\times 20.$

We know that $18\times 2=36$ and we have to add 2 + 1 = 3 zeros at the end of 36 to find the product of 1800 and 20.

Hence, $1800\times 20=36000.$

Thus, the cost of 20 such articles is ₹ 36000.
