the reciprocal of the hcf and lcm of two are 1/12 and 1/312 .if one of the number is 24 then other no. is  Select:
A) 126
B) 136
C) 146
D) 156
E) 166

Rationale: "reciprocal of the hcf and lcm of two are 1 / 12 and 1 / 312 so , hcf = 12 , lcm = 312 lcm * hcf = product of two numbers = a * b = > b = lcm * hcf / a so , other = 12 * 312 / 24 = 156 answer : d"
Answer: D
