Question:

The ratio of iron to nickle is 95:3 find the nickle in 980 kg of steel.

Answer:

The amount of nickel is 30 kg.

Given:

The ratio of iron to nickel is 95:3.

The amount of steel is 980 kg.

To find:

The amount of nickel in 980 kg of steel.

Explanation:

The ratio of iron to nickel is 95:3.

Let, the common multiple of the ratio be, 'n'.

∴ The amount of iron = (n ×95)

                                  = 95n

Similarly, the amount of nickel = (n×3)

                                                  = 3n

According to the problem:

(95n + 3n) = 980

⇒ 98n = 980

⇒ n = (980 ÷ 98)

⇒ n = 10 kg.

∴ The amount of nickel is _

(10×3) kg

= 30 kg.

∴ The amount of nickel is 30 kg.
