Suppose 2 kg of sugar contains 9 × 10 6 crystals. How many sugar crystals are there in 5 kg of sugar?

We have to find number how many crystals are there in 5 kg of sugar Given, 2 kg of sugar contain 9 × 10 6 crystals let 5 kg of sugar contain Y crystals Now As the quantity of sugar increases the no. of crystals also increases ∴ They are in direct proportion ⇒ 2 9 × 10 6 = 5 y y = 5 × 9 × 10 6 2 ⇒ y = 45 2 × 10 6 ⇒ y = 22 . 5 × 10 6 y = 2 . 25 × 10 6 crystals

Suppose 2 kg of sugar contains 9 × 10 6 cystals. How many sugar crystals are there in 1 . 2 kg of sugar?

We have to find how many sugar crstals are there in 1 . 2 kg of sugar Given 2 kg of sugar contain 9 × 10 6 crystals Let 1 . 2 kg of sugar contain Y crystales Since, Quantity of sugar increases the no of crystale also increases ∴ They are in direct proportion ⇒ 2 9 × 10 6 = 1 . 2 x ⇒ x = 1 . 2 × 9 × 10 6 2 x = 0 . 6 × 9 × 10 6 x = 5 . 4 × 10 6 Crystals
