The reciprocal of the hcf and lcm of two are 1/13 and 1/312 .if one of the number is 24 then other no. is Choose the correct choice:  A) 126  B) 136  C) 146  D) 156  E) 169

Rationale: reciprocal of the hcf and lcm of two are 1 / 13 and 1 / 312 so , hcf = 13 , lcm = 312 lcm * hcf = product of two numbers = a * b = > b = lcm * hcf / a so , other = 13 * 312 / 24 = 169 answer : e
Answer: E
