the reciprocal of the hcf and lcm of two are 1/17 and 1/312 .if one of the number is 24 then other no. is Choose the correct choice from the following options.
A) 126  B) 136  C) 146  D) 221  E) 266

Rationale: "reciprocal of the hcf and lcm of two are 1 / 17 and 1 / 312 so , hcf = 17 , lcm = 312 lcm * hcf = product of two numbers = a * b = > b = lcm * hcf / a so , other = 17 * 312 / 24 = 221 answer : d"
Answer: D
