Question

Suppose in 2 Kg. sugar, there are 9 x 10⁶ crystals. How many crystals will be there in 1.2 kg. sugar?

Answer 1

Let x crystals be in 1.2 kg sugar.

Then, 2 : 1.2 :: 9 × 10⁶ : x

Product of outer terms = Product of middle terms

⇒ 2 × x = 1.2 × 9 × 10⁶

Hence, the required crystals are 5.4 x 10⁶.
