Q1. The LCM of two numbers is 40 and their HCF is 4. If the difference between the two numbers is 12, then the sum of the numbers is Q1. The LCM of two numbers is 40 and their HCF is 4. If the difference between the two numbers is 12, then the sum of the numbers is
(A) 20 (A) 20
(B) 24 (B) 24
(C) 28 (C) 28
(D) 32 (D) 32
Answer: (C) 28 Answer: (C) 28
X * (X-12) = 40 * 4
X = 20
X + (X-12) = 20 + 20 - 12 = 28X * (X-12) = 40 * 4
X = 20
X + (X-12) = 20 + 20 - 12 = 28

(C) 10 (C) 10
(D) 14 (D) 14
Answer: (B) 7 Answer: (B) 7
7
=> x * 2x = 98
=> x2 =
=> x2 = 49
=> x = 77
=> x * 2x = 98
=> x2 =
=> x2 = 49
=> x = 7
