Question

Lin of 2 numbers are 14 times their hcf.The sum of lcm and HCF is 600. If one no.is equal to 280 find other number

Answer 1

Answer:

GIVEN: HCF+LCM=600, ONE NUMBER=

280

Let the HCF=X

LCM=14X

HCF+LCM=600

X+14X=600

15X=600

X=600/15

X=40

HCF= 40

LCM=14X=14×40=560

HCF×LCM=1st number×2nd number

40×560=280×2nd number

2nd number=(40×560)/280

2nd number=40×2

2nd number=80

So the other no. is 80
