Question

the LCM of two numbers is 20 times of their HCF and (LCM +HCF) =2520. if one number is 480, what will be the triple of another number?

Answer 1

Answer:

1800

Step-by-step explanation:

20*HCF = LCM.... equation 1

LCM + HCF = 2520 ... equation 2

put equation 1 in equation 2

21*HCF = 2520

HCF = 120

LCM = 2520-120 =2400

LCM*HCF = PRODUCT OF TWO NUMBERS

120*2400 = 480* X

2nd number = 600

therefore triple of another number = 600*3=1800

Answer 2

Answer:

1800

Step-by-step explanation:

lcm+hcf=2520

20(hcf)+hcf=2520

21hcf=2520

hcf=120,

lcm=20(hcf) =20*120==2400

now we have formula that lcm *hcf=a*b

120*2400=480*b

there fore b=600 but 3b=1800
