The HCF of two numbers is 21 and their LCM is 221 times the HCF. If one of the numbers lies between 200 and 300, then the sum of the digits of the other number is?
Answer & explanation
Correct answer: option 4
HCF = 21 Numbers → x, y
LCM = HCF × 221
divided HCF
xy = 221
13 × 17 = 221
x y
13 17
×21 ×21
273 357 → 3 + 5 + 7 = 15
