Question

1. What per cent of 2 kg is 200 g ? ​

Answer 1

Answer:

10% of 2kg is 200 grams

Explanation:

Let n% of 2kg = 200 grams

=> n% × 2×1000 grams = 200grams

/* we know that ,

1kg = 1000 grams */

=> (n/100) × 2000 = 200

/* % = 1/100 */

\implies 20\times n = 200⟹20×n=200

\implies n = \frac{200}{20}⟹n=

20

200

\implies n = 10⟹n=10

Therefore,

10% of 2kg is 200 grams
