LCM of two numbers is 56 times of their HCF, with the sum of their HCF and LCM is 170. If one of the two numbers is 240. Find the sum of two numbers.
Answer & explanation
Correct answer: option 3
LCM = 56 HCF
56 HCF + HCF = 170
HCF = 30
240 = a × 30
a = 8
ab = 56
b = 7
The other number = 30 × 7 = 210
Sum of the number = 240 + 210 = 450
