Question

150 kg of alloy containing copper and zinc in the ratio of 2:3.if the overall alloy should contain copper between 45percent to 55 percent,what can be minimum value of X?​

Answer 1

Step-by-step explanation:

150kg of alloy

copper and zinc in ratio 2:3

copper is 45

zinc is 55

x =45+55

x= 100

Answer 2

The minimum value of x is 100.

Step-by-step explanation:

Let the alloy containing copper = 2x and

the alloy containing zinc = 3x

To find, the minimum value of X = ?

According to question,

2x + 3x = 150

⇒ 5x = 150

⇒ x = $\dfrac{150}{5}=30$

∴ The alloy containing copper = 2 × 30 = 60kg and

the alloy containing zinc = 3 × 30 = 90kg

∴ x = 45 + 55 = 100

Hence, the minimum value of x is 100.
