1.	In a family, the consumption of rice is 4 times that of wheat. The total consumption of the two cereals in a month is 30kg. Find the quantities of rice and wheat consumed in the family
Answer» Let the quantity of wheat consumed in the month x kg. Quantity of rice = 4 times of wheat = 4x kg Quantity of rice + Quantity of wheat = 30 kg ⇒ 4x + x = 30 ⇒ 5x = 30 ⇒ 5x/5 = 30/5 (Divide by 5 on both sides) ⇒ x = 6 kg ∴ Quantity of wheat = 6 kg Quantity of rice = 4x = 4 × 6 = 24 kg

In a family, the consumption of rice is 4 times that of wheat. The total consumption of the two cereals in a month is 30kg. Find the quantities of rice and wheat consumed in the family

Answer»

Let the quantity of wheat consumed in the month x kg.

Quantity of rice = 4 times of wheat = 4x kg

Quantity of rice + Quantity of wheat = 30 kg

⇒ 4x + x = 30

⇒ 5x = 30

⇒ 5x/5 = 30/5 (Divide by 5 on both sides)

⇒ x = 6 kg

∴ Quantity of wheat = 6 kg

Quantity of rice = 4x = 4 × 6 = 24 kg
