Answer 1

Step-by-step explanation:

(Question 2)

Let a and b be the numbers.

Given, a = 165

We know,

HCF(a, b) * LCM(a, b) = a*b

So,

HCF(165, b) * LCM(165, b) = 165b

Also given,

HCF(165, b) = 660

LCM(165, b) = 33

HCF(165, b) * LCM(165, b) = 165b becomes,

660 * 33 = 165b

b = (660 * 33)/165

b = 132

Hence, a=165, b=132

(Question 3)

Let's g denote gold and c denote copper

Given,

g + c = 96

Also,

c is 1/12 of 96, we have

c = 96/12 = 8grams

We need to find g,

g + c = 96

=> g + 8 = 96

=> g = 88grams
