Question

1. The sum of HCF and LCM of two numbers is 435. LCM is 28 times the HCF
If one of the numbers is 60, find the other number.
​

Answer 1

Answer:

let HCF and LCM be a and b

let the numbers be x and y

given

a+b=435

b=28a

x=60

a+28a=435

a=15

b=420

HCF ×lcm = product of numbers

15×420= 60×y

y= 105
